If a user agent change makes the software slower for a platform then that's not exactly an accident so somebody must have had the intention to make it run buggy.
This has nothing to do with 'making it run well on platforms you care about' but it is 'making it run bad on platforms you don't care about'.
It takes more code for the software to act in this way (this is what proves this is intentional and not accidental), and more support to boot.
