What about comments?

I don’t know if it makes much sense – but I really like the idea!

You are right, this would mean to update the post – and therefore it would be necessary to scan all existing comments to collect all tags. On every saving of the post and also of any of the comments. Would slow down speed a bit.

I keep that in mind. Thanks.

Plese do not forget to rate the plugin if you like it.
