I can't find any recent publication that justifies this change.

Hodgetts et al. 2019 do not support this for Europe:

"541 Ignatov, Fedorova, et al. (2019) established the genera Anomodontopsis (for Anomodon rugelii) and Anomodontella (for Anomodon longifolius), and resurrected Haplohymenium (for Anomodon tristis). Although Ignatov, Fedorova, et al. (2019) show different lineages ‘within the Anomodontaceae’, the same study gives support for a clade that includes all the species of Anomodon s.lat. except Anomodon attenuatus, so a relatively conservative approach is adopted here in order to avoid the unnecessary proliferation of small genera."
