Escaping might be an issue.
Another approach could be following out headline format
#+name: Title :tag1:tag2:

In any case, I am not too concerned about the semantics at this point.

In order to implement tag support in named blocks, you will need to add
it to many places in Org, like parser, export, babel, user commands,
etc. It is not trivial. And do not forget about backwards compatibility
and, for example, third-party export backends.

The latest progress is a bit of discussion on parser-based font-lock
keywords in emacs-devel. See
https://yhetil.org/emacs-devel/87wn9srn9n.fsf@localhost/

The code status still requires some decisions to be made about code
design of the parser. In particular, the current (albeit working)
implementation will make it difficult to apply arbitrary fontification
order for parent/child elements. Like in
https://orgmode.org/list/m2mtdp2cwo.fsf@ntnu.no

And I need to write tests, add faces to all possible elements/objects,
and re-factor the code into shorter function.

I have not had much time to work in these lately because of the upcoming
Org release.
