CLDR does support abbreviations, but a couple steps of indirection are
required.

You have to take the tzid and an effective date to find out the
"metazone", then the "metazone" knows what its abbreviations are. I've
advocated in the past for tz files to identify the metazone of each
transition because the CLDR should really not be responsible for keeping
this up to date.
