It's irrelevant if they are comparable. This is a system-wide change that has
potential to cause performance regression. By how much -- not clear. Hand-waiving such
concerns is extremely disappointing in the face of the scrutiny given to
https://pagure.io/fesco/issue/2817. So, please get inspiration from that proposal and do
benchmarks.
You're basically making a political statement, so I'll just leave that
bit for FESCO to deal with.
