Why does audacity flatpak need filesystems=host permission?

[aleprovencio]

Hello,
I was actually trying to use persistent=.audacity-data and bumped on issue #20, but I realized it only worked if filesystems=!host is used.

So my question is, any particular reasons for this flatpak have host access?

I would be ok with restricting to home. There no way tighter as audio plugins are a mess and the only thing we'd gain is stuff not working, mysteriously.

tbf not being the original packager, I don't know the original rationale.

Unfortunately, filesystems=home would also prevent persistent=.audacity-data from working. Just for the sake of learning, which plugins you've found that need such access?
