Picard 2.2.2 is available, better performance for Windows and macOS

I am certain this has come up before.
But I couldn’t find, nor remember what was said last about this, so I am taking the liberty to raise it again here today.
(And no, I am not very savvy with github, tickets etc.)
My apologies if this bothers anyone.

Picard writes tags to a tag name that is ‘set in stone’ internally.
This works well most of the time, but depending on other software you are using it will sometimes present problems.

To keep this request/suggestion simple to understand, let’s take one specific example, narrowing it down to one tag in the Vorbis format:

There is something called ‘disc subtitle’

Picard will write ‘DISCSUBTITLE’ for it.
But some other software will be using ‘SETSUBTITLE’ for it.
And other software perhaps uses ‘SET SUBTITLE’, or ‘DISC SUBTITLE’.

For situations like this, it would be very useful if it was possible to set some customised tag mapping in Picard.
Not just for this specific Vorbis example, but also for e.g. id3v2 TXXX tags. Some software will have specific non-TXXX tags for a tag, others will need TXXX for them.

Is this something that is considered, or even feasible for upcoming versions of Picard?
