Yes, and the Philippine poliogyna group remained within the insular SE Asian White-browed SW in 2019, and remains so, while the undescribed Mindanao taxon is given species status. This taxon does not even get a mention in IOC. Given that the lists are supposed to be converging, should this not be a proposed split?

It won't pop up on IOC until someone actually describes it, as IOC only includes formal . Clements can put it as subspecies "group", because ebird also has non-taxonomic entities, such as hybrids, genus or larger taxonomic groups sp, and so on. I think there are other undescribed forms in the Clements Checklist as well.
OK I didn't realise IOC excluded undescribed. Clements does not have this or the cuckoo-dove as 'subspecies groups' though, which would be uncontroversial.

It's not obvious to me why that would be uncontroversial, as it's making an assumption about the taxonomic affinities of a form with no official description. Why are you so confident that the Palawan Cuckoo-Dove is part of one particular species versus another?
As for the full list, as of 2021 it's these 40 species. At least a few of these have been officially described since then - the "San Pedro" Tanager (now Inti Tanager), the New Caledonian Storm-Petrel, and (if I'm remembering correctly) the Meratus birds.

All are candidates to be species or are there also subspecies?

I'd imagine both? They are undescribed, which means the work hasn't been done yet to properly place them as a new subspecies of a known species or a completely new species.

In the Clements checklists, they stop short of saying that a subspecies group has some taxonomic significance. Here's what it says on their website:
A “group” is a distinctive (field identifiable) subspecies or group of subspecies. The group is not a formal taxonomic unit, but often represents a potential future split (and so groups are a valuable taxonomic tool for the savvy birder).

Both, as 'Togian Jungle-Flycatcher (undescribed form)' for example has been described, as the assuringly named omississimus, a subspecies of Sulawesi Jungle-flycatcher (though when first discovered it was thought to be a good species, until specimens obtained), along with several other of the above, which includes described species:
Flycatchers and fantails: new songbirds discovered on tiny islands
Five species and five subspecies found in Indonesia in the largest discovery of its kind in more than a century
