I would say software stability and artistic integrity thus far are the only redeeming points of this game. Otherwise, most of the changelogs are often focusing on bug fixes with minimal hentai content in between patches. For the whole franchise, it would be their 10th Anniversary in 2024 (Malise and the Machine was released in 2014, put on hold since 2017/2018, while Pure Onyx developed after Malise and the Machine put on hold shortly.)
Few updates prior to the July/August Test Release only have one or two new animations while the rest are yet another variation of the same theme (i.e. Vioreaper 3x for Onyx ported for the Femcop, etc.)
TL;DR
This will be finished like never.
