Why Sketchup Need to handle heavy poly models for 3d render?

sketchuh

hi you all, this seems like beating a dead horse. but hey this will be my first and last post on this topic.
so bear with me.

sketchup users who think sketchup doesn't need to handle heavy models for 3d rendering have their reasons. Their reasons are:

you can export and compile sketchup models into a 3rd party rendering program like thea. thea can handle very high poly counts. BUT to me doing interior rendering job(i'm no pro at all), my workflow is quite "messy". i like to try different models for one particular scene. if i don't like that plant or vases or books... in that scene, i do a preview render then i can change them. the reason i don't think this rationale will work for me is, my scene is not finished or finalised. if i keep importing and exporting to 3rd party rendering studio. the time will be longer. if i can just STAY in sketchup to do the rendering testing, the process will be faster.
you can import proxy models of heavy models. same thing. it won't work for me. what if i want to make some changes to that heavy models? the proxy models can't be changed in sketchup. i have to reimported back to my current skp file. also proxy models can be buggy. if I sketchup can handle heavy models, I can just stay in sketchup. happy!
simply, if sketchup can handle heavy poly models, i don't need to do so many workarounds. because workarounds waste time. That is my point here. if i can stay in sketchup, i can save a lot of time. i can have more time tweaking and creating. i can go thru many iterations or minor changes directly in sketchup.
I think i will move away from sketchup if i have to import heavy models for a scene. i Don't like workarounds.
I hope i will find a program that will handle heavy count models and do nice fast rendering.
i DO like sketchup for it's measuring tools, snapping tool... it helps me quickly create very accurate models.(i build custom furniture models in sketchup).

if my post offends you, because you think it's because my lack of expert knowledge of sketchup. you are prob right. but hey a lot of people want to do 3d interior rendering in sketchup have the same problems.

like others i don't think sketchup will ever be able to handle high poly models.
