Improve the user experience for fetching commits from slower endpoints
For fetching a large number of commits we see that some GRPC calls can take as long as > 20 seconds https://gitlab.com/dankm/freebsd-ports/commits/master/databases/php73-odbc/Makefile.
Where this does not always result in a 502 on the user I think it would be a much better experience to fail faster and offer an alternative, similar to what GitHub does https://github.com/freebsd/freebsd-ports/commits/master/databases/php73-odbc/Makefile
