as soon as names are settled, one should make a PR and unify all of such imports.

I thought we no longer want to do renames?

indeed, but see my note:

at least now that almost everywhere we use paint-support as support, having consistency is better IMO + makes sed-ing much easier. As mentioned, I'm more than happy to kill all of these as soon as we are done with paint -> palette.

Is it really worth to re-export? This stuff is in the same crate, I don't see a point - it will just introduce ambiguity.

AFAIK: This stuff, similar to other re-exports of the module are needed to be accessed from within the macro. I learned this by example. @bkchr can probably either explain more or correct me.

Can you elaborate why is Send + Sync required? I wouldn't expect to see that in any part of runtime.

Good point, I didn't really care much since I have seen these two in all SignedExtension type. For instance:
substrate/paint/system/src/lib.rs
Line 853 in 0f87c92
So I assumed it is okay. But I will look it up.
although, we use Send + Sync in Member which is used around the runtime, so just by observation, I would not assume that we ban them in runtime. Although it does makes sense that a single threaded runtime should not really need them.

Needed due to AccountId being Member.

Copy is a pretty strict, why not just Clone?

I did face the dilemma and at the time the rational was: while we are making Type Info be generic but we currently know that we'll use it with a type that has Copy and this makes the syntax much much easier for now. If we see Copy as merely a marker that clone is cheap, I think it is fair to say that this bundled information will always be cheap to copy.

naah made it clone, was easier than what I thought to refactor.

Makes
SignedExtensionindependent of the type of the weight data, allowing a potential user to actually not have any sort of weight or class by settingtype Info = ().Moves the weight related stuff to support, since they are part of our opinionated runtime.
Looks like we need a follow up PR to move all the extrinsic stuff to paint, but I'll do that in a follow up, since this has a bit of logic change in signed extension.
