The issue of Transnistria independence is current and relevant IMO because: (a) Russia has troops stationed there (b) Moldova, unlike the Ukraine, has neutrality enshrined in its constitution (c) Transnistria now has some independence from Moldova
(b) & (c) type agreements were part of the Minsk Agreement with respect to Donbas/Ukraine up to 2019 when Ukrainians passed a referendum to join NATO and then elected the current Government to, among other things, implement that.
Hence the war now in the Ukraine but not in Moldova (yet)
