The translation sharing option can lead to Ubuntu translations to not be imported

[Sebastien Bacher]

Ubuntu packages having their translations shared with upstream don't get new strings imported from tarballs on upload.

Example, https://translations.launchpad.net/ubuntu/impish/+source/evolution/+sharing-details

Colin wrote about the topic

'so if has_sharing_translation_templates is true, then the translations upload job only considers .pot files
That is true if the source package has a sharing partner *and* the sharing partner has "current" templates
Which is exported on the webservice API for that template as the "active" attribute'

The behaviour is problematic for Ubuntu because often the upstream vcs-es are outdated imports so it means we don't get updated translations

Everyone now and then we do manual editing to disable the sharing for important desktop packages but the option seems to turn on again (either someone is doing it manually to help or the default for a new Ubuntu serie is not following the value the previous serie had?)

Could we get the behaviour of this option revisited?
