Any decrease of performance isn't "normal" and removing something isn't a real solution to that, nor would it fix anything regardless. If just injecting it on its own impacts performance then report that so we can fix that.
Because it was reworked, has nothing to do with any blatant things or whatever the assumption here is.
Not in the slightest. It should only take 5-15 seconds to inject, anything more is due to a network bottleneck on your end or possibly another issue, both of which can be addressed.
By the way, I don't quite understand the general narrative of "blatant stuff isn't going to get supported anymore". It's been untouched for 4 years already, so this isn't a new decision or anything. Before, I mentioned that we could just leave them in, but now I realize that this is causing an issue. It seems that we have a community of blatant users who were hoping for blatant modules or were under the impression that these features were more than just a legacy feature that was added half a decade ago. So it looks like we'll need to remove those now.
But FYI removing those will do absolutely nothing to fix any issues you might have mentioned. This will not be done for the purpose of fixing crashes, lag, etc, anything that you mentioned, you will still have all of those problems if they happen to exist for you.
No it would make absolutely no difference.
Not normal. To be more clear about what I'm saying - suppose I removed every single module for you, it would still take 59 seconds.
