I propose to announce at the next release (v1.3) that strategy X will
be dropped at the next next release (v1.4), explaining the daemon
upgrade and/or point to documentation.

And we should keep lzip-9 (users with a weak network) et zstd-19, as
Pierre and Guillaume are proposing.
So gzip would stay until v1.4, i.e., more or less 1 year (or 1.5 years) more.
All the best,
