Okay, let's back up here and put aside the fact that we disagree about which code you need (I still think your forklift is covered under D14.3 not D14.1). And, make sure there is no attitude, from either of us (not just telling you to watch it).
So, let's see what the section in question applies to. As stated, less than 5k psi tensile.
So, how will that work under production applications? Welding of the engine cover panel. Welding of a part under compression that only needs to be held from shifting under very low loads so low tensile requirements.
Certainly not the carriage or forks. Not the main framework or engine supports. Not the axles or spring mounts.
So, in order to give you a clear and accurate answer, we need to know what exactly you are fabricating, welding, on these forklifts. And, are you a manufacturer's employee or what is your job? An outside verification inspector?
At first glance, my opinion would be that the welders would need to be qualified. Having worked on log yards, construction companies repairing equipment, and for myself as a general fabrication shop that repaired heavy equipment, I know that there are times you are working on truly non critical components but far more times when those components are critical either for the product load or safety of the operator or those near by. Most equipment work has a safety factor even if it is not a tensile load critical part that must be considered. Guards, shields, ladders, seat brackets, control handles (gear shift, boom lift and tilt handles, etc), all need to be sound in their repair or original manufacturing.
It is not an item that I would be looking for a loophole in order to save a few bucks by not qualifying my welders. And, for many applications, D1.1 qualifications can cross over and be acceptable. Dual certifications are possible between many of the codes and D1.1 and D14 codes are very similar for welder qualification purposes. Especially if it would be something that may be under your section 7 query.

Ok, so I don't have my D14.1 with me at the moment, and I hate to make assumptions, but here goes.
I don't believe the D14.1 section in your original post may be interpreted as allowing unsupported welding for secondary welds.
I believe the wording is meant to point out that all of the additional requirements that are specified for Primary welds, such as design concerns, prohibited joints and NDE requirements, are not required for secondary welds.
I belive D14.1, just as D14.3 does, relies on the design criteria in D14.4 - Specification for the Design of Welded Joints in Machinery and Equipment.
This Specification, in the Workmanship section 6.1.5 states:
" 6.1.5 The Manufacturer's adherance to this specification shall include responsibility for the following:
(1) Producing welds as designated on drawings by appropriate symbols and note with sufficient detail...etc...etc...
(2) Providing and using written welding procedure specification.
(3) Ensuring qualified welders are used to make welds.
(4) Recording and maintainng results of all welder performance and procedure qualification tests.
(6) Inspecting the welds to the requirements of this specification
etc. etc. etc"
Perhaps the D14.1 isn't painfully clear on the exact meaning of the section you posted (AWS ambiguous, surely not), but the possible interpretation you metioned is too far fetched.
I would be willing to bet that your Internal or Customer's specification would allow no unqualified welding on product as well.
