brew uses --installed [email protected] reports something wrong

[josser]

Hi!
I'm trying to avoid having too much packages installed, and today I've found that I have both python 3.8 and 3.9 installed.
So, I've decided to understand which packages require [email protected] and found this command in docs:

brew uses --installed [email protected]
It reports this list:

cairo - https://github.com/Homebrew/homebrew-core/blob/master/Formula/cairo.rb
harfbuzz - https://github.com/Homebrew/homebrew-core/blob/master/Formula/harfbuzz.rb
libass - https://github.com/Homebrew/homebrew-core/blob/master/Formula/libass.rb
midnight-commander - https://github.com/Homebrew/homebrew-core/blob/master/Formula/midnight-commander.rb

but neither of them have 'python' in 'depends_on' section.
So, I guess 'brew uses' resolve [email protected] in sub-dependencies.
If this is correct guess, is there any way to found this deps?
Thank you!

You can run it with --recursive https://docs.brew.sh/Manpage#uses-options-formula

@SMillerDev oh, I forget to tell. I've tried adding --recursive but it doesn't change results

Ok, this is not the answer to original question, but I have found the way to get rid of [email protected]
I've uninstalled midnight-commander, ffmpeg and all of their leaves ([email protected] and [email protected] was there)
Than I've installed them back and no [email protected] was in deps.
