How many resources? Just what is involved?

The point of autoload is to load just a pointer to a target, rather than loading
the target itself. Why would 7000 additional autoloads be a big runtime or
load-time burden?

I'm not claiming it is not a big burden. I'm asking why it is. I don't see why
it would be so costly for Emacs to record 7000 vars and their target files for
loading.

I haven't seen any explanation or cost analysis so far. All I've seen is Stefan
screaming, essentially, "NO! DON'T!!!". I'm not saying he's wrong. But what's
wrong with seeing some analysis of the cost involved?
