Store score files in backward-compatible way

Your idea

I wish there was an option to store a score in a format that is compatible with older versions of musescore.

Problem to be solved

I have been encountering some issue with the recent musescore versions and the easiest workaround is usually downgrading. However due to the way musescore binds the score file version to the musescore version, I am not able to work on the score I just created in the current musescore version, with older musescore versions.

There probably aren't that many changes in the file format, but it seems to me that there is a general block: You saved this with musescore version 4.7.3 → you cannot open it in any earlier version.

Another idea was allowing to override this block at one's own perril, but this is not possible, because then the older version of musescore would have to changed.
