I really think it comes down to personal preference and how far you want to go. Fundamentals are the foundation on which you build your entire game and it's up to you to determine just how solid you want that foundation to be.
I know some players who are APA 6s who simply cannot go any farther due to their fundamentals being off.
Obviously some pros have kinks, and hiccups in their fundamentals (looking at you Busty) who still play at the highest levels.
My stance is, if you can make a fundamental change that improves your game without it hindering another fundamental or your body then do so. If it takes you two weeks of changing a small kink and then you never have to worry about it again then do it.
The biggest improvements regarding my consistency at the table have come from fine-tuning my stroke and fundamentals further and further.
You can think of it like laying the foundation of a skyscraper; the higher you want to go the more solid your base needs to be.
