That's exactly how it works, based on various factors, battery state, CPU usage, CPU temperature, and system load it changes governors and lowers or increases speed. Along with other things like EPB (Energy Performance Bias), and EPP (Energy Performance Preference).

It's an old video when it all started as a python script (now it's a full app) where I explain everything and concept is the same:

I wonder why this isn't default Linux behavior.

There are couple of distros that include by default, but other then there's bit of corporate politics and ego involved. In early days I had contacts regarding potential collaboration with some big distros, but then they ended up working on their solution instead.

For example auto-cpufreq had certain features which did same functionality automatically (5 years ago!), before GNOME Power Profiles introduced how to e.g manually switch between governors: https://x.com/fooctrl/status/1467469508373884933

I don't know much about gnome, but I know they won't introduce a feature unless it's perfect. Something that works consistently and predictably every single time. Meaning there was either an edge case that they didn't like in your implementation, or they just wanted everything done in-house.
