I only started to use sequoia pgp as a replacement for GnuPG recently,
due to performance issues on my old offline Notebook and wanted to
mention that the packet split functionality is there included too.

I would say if you use sequoia pgp as a replacement for pgpsplit it
should work the same.

At least it's worth a try, in case you find no alternative and chances
would be low that in the future such split functionality would not be
included in future versions of GnuPG.
