comment Color gradient fill between three corners of a triangle
Filling a polygon using triangles is not an easy task. I looked into this recently for another system and even for quadrilaterals it's not trivial (see loopspace.mathforge.org/discussion/38/filling-a-quadrilateral for what I came up with). So I think you need to think a bit more carefully about what you want the result to be.

comment Parameters for newly-defined shapes
@HenryDeYoung That might be worth a question of its own. They're useful things to know about (and I don't claim to know them fully) and a good explanation with examples would take up more than a comment could hold.

comment How to make the length of a car moving on a roller coaster track remain unchanged?
@CharlesStaats My answer currently has 2 undelete votes on it. It needs one more to undelete it. I suspect that there'll be someone in chat who will happily supply the 3rd vote. (I won't delete it again - I've made my point - but neither will I undelete it myself.)

I'm sorry, but I consider "This question has not received enough attention." to be a bit rude considering the amount of attention it has had and am consequently deleting my answer.

comment How can I decide whether a key has had .value forbidden applied?
I guess the question is as to how widely you want your code used. If only by you, then you can be aware of its limitations and not do the things that break it. If by others then you can guarantee that it will break!

comment How can I decide whether a key has had .value forbidden applied?
Looking at the code, you can't. The .value forbidden works by appending a test at the start of the key's code and no register is kept of which keys have had this added to them. Maybe you could test #2 and if it is empty then pass \pgfkeysnovalue instead of nothing.

comment Using the TikZ spy library to spy on a pixel value in beamer
Any chance of upgrading? It's really worth it.

What version of TikZ are you using? It works for me with TikZ3.0.

comment Loop with tikz index problem
Sounds reasonable! I don't think \foreach can handle emulate \while loops so that makes sense.
