A question for devs-why not make jit run faster then gpu thread ( allow VPS>FPS ) ?

Thank you skid and neobrain for detailed explanation ! So I guess desyncing cpu and gpu is out of the question,because we would get black screen, but there is still interesting issue here...

VPS > FPS means that the GPU can't process the amount of frame render request sent by the CPU, i.e. you're GPU-thread bound (a faster GPU will help here but is not a panacea because the GPU thread is also a fair bit CPU dependent)

So we have example 1 where VPS=FPS and example 2 where VPS>FPS.
Issue I am desribing is that we can have both of these examples on exactly same hardware in exactly same game in exactly same place.
Only thing which decides if it will be VPS=FPS or VPS>FPS is dolphin options idle skipping and vbeam, fact if gpu can keep up or not with number of frame render request sent by cpu doesn't seem to make any difference.
Or in other words,were I to disable vbeam and/or enable idle skiping, in that scene in SMG2 I already posted screenshoot of,I would get 34 FPS AND 34 VPS INSTEAD of 111 VPS !
This is the issue I am talking here...it still seems VPS is SLOWED DOWN somehow with default dolphin options..
I can make another screenshoot showing 34 FPS and 34 VPS if needed...
