You removed types completely and changed all the usage. That was a lot of work... Why not keep the types in the defs interface but point them to the git defs?

Keeping the following would reduce the impact to almost nothing:

INTERFACE zif_abapgit_definitions.

TYPES: 
  ty_sha1               TYPE zif_abapgit_git_definitions=>ty_sha1,              
  ty_file               TYPE zif_abapgit_git_definitions=>ty_file,               
  ty_files              TYPE zif_abapgit_git_definitions=>ty_files,
  ty_files_tt           TYPE zif_abapgit_git_definitions=>ty_files_tt,
  ty_file_signatures_tt TYPE zif_abapgit_git_definitions=>ty_file_signatures_tt,
  ty_comment            TYPE zif_abapgit_git_definitions=>ty_comment,
  ty_item_state         TYPE zif_abapgit_git_definitions=>ty_item_state,

There are a few more I would move or you might need in /git:

ty_chmod
ty_create
ty_commit
ty_commit_tt
ty_expanded
ty_expanded_tt
ty_ancestor

c_git_branch_type
c_head_name
c_git_branch
c_type
c_state
c_chmod
c_author_regex

well, having the same definitions multiple times, then it should be changed sometime anyhow?

yea, there is always more to move

this is just a start

will see how much extra breakage there is 😁
