No, it's worse than that. Consider the following questions. Most people
will say that tags "obviously" have a particular answer for each
question, but they disagree on which answer it is...

First: how do tags relate to categories? Are they independent, a
refinement or a replacement?

Second: which of the following are tags suitable for? Searching.
Browsing just using 'ls' etc. Browsing using tools (e.g. a website or a
package manager command). Using as dependencies.

Third: are tags a property of ebuilds, of packages, of a repository, or
entirely external?

Fourth: do tags in any way identify a package?

Fifth: how do overlays fit in to all of this?

From the previous times we've had this discussion, I very much get the
impression that right now "we'll use tags!" is an utterly nebulous
answer to a problem that's about on par with "we'll replace all use of
oil by green technology by next week!".
