Would it make sense for folks at Calconnect to chime in on this?

>>> TZID appears to be the only parameter defined 5545 whose value can not be a quoted string.  This is problematic in that time zone IDs such as "GMT-03:00" are beginning to appear (note the embedded colon).  RFC 6868 has no mechanism to quote a colon character, as it relies on such characters appearing within a quoted string.  I see no technical reason why a TZID parameter can not be quoted, and existing implementations already accept quoted TZIDs.
