stumbled upon this again when checking out old(er) patches without comments,
some higher level comments inline.

hmm, maybe we should go for a layout with one field per row, but besides that a
short description about what it controls, like:

Label [ Field ] Description

Where the descriptions are sorta in the style of the CPU flag ones for VM CPU
edit, i.e., provide some context and hint of what this does.

Because max-workers "VM Worker Count" is not easily understandable IMO, i.e.,
one could think that's parallel backups done by separate workers (like e.g.,
max worker is used for migrate-all or HA LRM parallel workers)

disabling that when ZSTD is not selected might slightly improve UX too.
