Is there a problem if we add ~4 thousand automatically generated obsoletes?

Would adding automatically generated obsoletes to 3624 Python packages have any 
observable negative impact (e.g. on the repodata size or time to resolve deps)?

I think that would increase the size of the primary repodata...

I guess by number * length of obsolete, so might not be that bad?

It would likely affect dnf processing time as well, but not sure how
much.

It seems like something to try and avoid if possible.

Hi,
point taken. I've checked with the dnf team as well, and they're of the 
same opinion. So we won't be turning on the automatic Obsoletes in 
Fedora, only in ELN.

Thanks for the feedback!
