For golang-github-masterminds-semver-dev, I think create a new branch
d/experimental on salsa and push your stuff there, and we make a team
upload to experimental. Makes things better maintainable that way - you
can check this[1] as an example for how to do it
The way you have done it on your personal fork looks good, you just need
to replicate it on the salsa team repo with d/experimental branch
instead of master.
Also, please consider to ask the maintainers of this package
({foka,bernat,czchen}@debian.org} if they are fine with creating a new
branch and uploading to experimental -- just to ensure we are on same
page.
