That's a complaint against how time zones are themselves named and organized. See https://ftp.iana.org/tz/tzdb-2022b/theory.html for all the gory details.

Using +4 or +5 explicitly instead of a time zone when DST is relevant is bad juju. Then your arithmetic can become silently wrong in subtle ways when it cross a DST boundary.

Ah I see, I didn't understand the original question properly. "Choose one side of DST or another" was meant for the time literal, not the TZ. That's my bad.
