Heyo znavko,

It's one of those systemd-only ‘standards’[0] (hence the ‘Linux’ 
misnomer).

Yes, these subtypes are mostly ignored and treated as equivalent 
the regular ‘20 Linux filesystem’ type.  I don't know what happens 
with software that predates/ignores this ‘standard’.

Their only use outside of systemd is to provide a hint for humans. 
For example, I use ‘Linux root (x86-64)’ for my root partition 
because ‘fdisk’ doesn't show partition labels by default.

None.

Kind regards,
