The general consensus is that competitive programming is competitive so if you're going to choose a slower language (like Java or especially Python) you need to be ready to deal with the potential setbacks and advantages of your chosen language. It's fair to say that Codeforces isn't supposed to accommodate your language choice especially if it's a poor one that is known to be slower than something like C++. HOWEVER, Python version on codeforces is currently 3.8 (out for 4 years) and versions 3.11 and 3.12 both bring speed improvements (3.11 for a lot of stuff (https://docs.python.org/3/whatsnew/3.11.html#:~:text=Python%203.11%20is%20between%2010,See%20Faster%20CPython%20for%20details.) and 3.12 for comprehensions (https://docs.python.org/3/whatsnew/3.12.html#:~:text=This%20speeds%20up%20execution%20of%20a%20comprehension%20by%20up%20to%20two%20times.)). I know loads of people use PyPy (and it does seem to work very well, cf. https://i.imgur.com/v9iOJnw.png) but it would seem relevant to allow newer version of Python (**I would even argue it will help lower the CPU demand on codeforces servers since both versions are known to be faster** so realistically ... why not ...).

I've just started codeforces so maybe this has been discussed before but I haven't seen any topics talking about it and i honestly don't think there'd be any drawbacks in getting a newer, faster version of Python on the website.
