That would require inventing names for time zones, and we try to avoid doing
that when possible. The goal is to describe timekeeping practice, not to
prescribe it. In hindsight the tz database could have supported having no
abbreviation for zones where abbreviations are not commonly used, and this would
have avoided some similar problems elsewhere where we use "zzz" for time zone
abbreviations in some cases; but this would have entailed some confusion and/or
compatibility hassles at the time the database was being introduced and it's
impractical to revisit this design decision now.
The situation with MSK is not unprecedented. For example, in the tz database
PST stands for "Pacific Standard Time" in the United States, and for "Pitcairn
Standard Time" in Pitcairn, and corresponds to UTC-8 in both countries. This is
entirely analogous to MSK standing for "Moscow time" in Russia and for "Minsk
time" in Belarus and corresponding to UTC+3 in both countries. For timekeeping
purposes it's often a bit simpler to use the same abbreviation for the same UTC
offset even if the abbreviation is ambiguous, and this hasn't been a significant
technical problem in practice.
