Thanks, now I understand basically how components work.

In case it's useful for someone:

debian/watch was changed so that it knows how to create an orig tarball
for the component also. And gbp.conf was changed to set the
--component=twemoji-parser option, so that gbp import-orig will import the
component's orig tarball as well.

>>> $ gbp buildpackage -us -uc --git-ignore-new
>>> gbp:error: Couldn't find upstream tree 'upstream/13.0.1+_13.0.0^{tree}' to create orig tarball via pristine-tar

It turns out the upstream version remains the same (does not include
component version).
