Semicolons are necessary, used, and need to be evaluated by tools. The
alternative is a massive change to the definition and existing use of many
tags, something that seems far more unreasonable. It's not ideal to create
new tagging schemes that require them, but IMO, we have to deal with the
ones that are there.
What probably bothers developers is not wanting to decide arbitrarily which
icon to show, and not wanting to invent a whole new metadata scheme to
decide priorities (thought this problem exists also when there are both
amenity and leisure keys present, for example). Personally, I would rather
see an arbitrary priority than nothing at all (the current state).
