Python bin installer is here:

Under "Packages targeting the Kindle 5" > "Python 2.7 & Python 3.9".

As for plug-ins and hacks: all that is highly dependent on users needs and habits. Like it is not the same if someone regularly needs to read bunch of old mobi books vs someone that reads azw3 99.99% of the time, even when both have in common say desire to use custom fonts.
Why if that? Well, in order to have & use a custom font in mobi format user needs to use @NiLiJe's FontsHack. But custom fonts are already available on stock firmware for books in azw3 or KFX format, so the fonts hack would be redundant for those people that don't read old mobi format.

Basically in the past there were many more things missing on a Kindle that regular users would consider to be basic functionality and thus people "had to" install hacks... but in the last couple of years Amazon has finally added most of those : native support for custom fonts, support for making the text bolder, support for using the cover of the book you're currently reading as a screensaver.
Also many people who in the past had to jailbreak and mess around with editing system files in order to redefine text sizes that are offered in Aa menu (because of the problem that one size is to small and the next one is waaay to big) now can fix that problem without needing jailbreak at least for book in azw3 format by creating "FONT_RAMP" file on Kindle drive. There is also "CONTENT_FONT_RAMP" to do the same thing for KFX books but unfortunately THAT still requires jailbreak and doing a tiny modification inside a JAR file in order to enable parsing of that "RAMP" file. Which is what I've done for my PW3 and will have to do again on my PW5.

Of all long-standing gripes Kindle users have had for past 12-13 years basically the only one Amazon hasn't addressed is the ability to have more granular control of margins. (well they did "address" that : they've changed something and now changing hardcoded values for margins inside system JAR files no longer works

).

Those things were reasons for 98% of jailbreaks i the past

Nowadays the main reason is wanting to use KOReader. And group of people that want custom screensaver but don't want that to be book cover

Other then those all that remains are some quite niche needs and use cases for "power users". Like wanting / needing Python runtime
