Thinking more and looking at "ETRS89-NLD [AGRS2010] to ETRF2000 (1)", I
see it is a noop transformation, so with no time dependency... How does
that fit with the fact that ETRF2000 is dynamic. I see that "ETRS89-NLD
[AGRS2010]" uses DATUM["AGRS2010 (ETRF2000)") and has
ANCHOREPOCH[2010.5]. So I'm thinking the output coordinate when
applying "ETRS89-NLD [AGRS2010] to ETRF2000 (1)" is at coordinate epoch
2010.5, right? Shouldn't the PROJ pipeline +proj=set +v_4=2010.5 ?
Same question for ETRS89-FRA [RGF93 v2] to ETRF2000 (1) and ETRS89-FRA
[RGF93 v2b] to ETRF2000 (1) with are both no-ops. Shouln't output
coordinate epochs be respectively 2009 and 2019 per their anchor epoch ?
