Hello Gresko8,
Assuming this module does what it sets out to do, it will be a crucial link between the COOKiES module and the Google Tag module for users in e.g. the European Union who need to implement Google's Consent Mode in order to get accurate analytics tracking data.
Is there anything we can do to help get this module out of the sandbox?
I suspect the COOKiES module maintainers will be keen to promote this module - I've popped a comment here in their issue queue:
https://www.drupal.org/project/cookies/issues/3274966#comment-15127880 ✨ Add support for Google Tag Manager consent storage Postponed: needs info

Miscellaneous
Why not just post it as a patch/MR with the whole submodule stored in "modules/cookies_gtag_consent", just like the existing "modules/cookies_gtag"?
This was already done in ✨ Add GA4 snippet support in cookies_ga Fixed .
It might be worth updating the sandbox project's page to note this?
