Question about doveadm altmove

Hello.
We are running dovecot 2.3.13. Full doveconf -n output below
In 2.3.14 Changelog I found this:
- Remove XZ/LZMA write support. Read support will be removed in future release. We are using mdbox + XZ/LZMA for alternate storage (messages older than 2 weeks are moved to ALT storage via cron job), so we must convert from XZ to another thing (maybe zstd or bz2).
Why can't you just pipe the output of "doveadm altmove" command through an external command to do the XZ/LZMA compression if dovecot no longer supports it internally?
From doveadm-altmove (1):
This command can be used with sdbox or mdbox storage to move mails to alternative storage path when :ALT=<path> is specified for the mail location.
And that's set in stone.

So what are the issues with xz? Security? Crashes or viruses on expanding invalid archives?
Any update on this? Dovecot 2.3.14 makes doveadm altmove -r functional?

zlib plugin, as far as I know, only supports zstd, gzip, bzip2 and lzma/xz compression. The last one is being deprecated.
I have found this interesting post in the mailing list:
https://dovecot.org/pipermail/dovecot/2021-February/121329.html
Same problem here with Dovecot 2.3.13, "doveadm altmove -r" is not moving anything from alternate to default storage. I fixed this by reverting this commit:
https://github.com/dovecot/core/commit/2795f6183049a8a4cc489869b3e866dc20a8a...
Is this fixed in 2.3.14 ? Does doveadm altmove -r works as expected in 2.3.14?

Any update on this? Should I fill a bug-report for doveadm altmove -r not working?
