For vector layers, you can apply filters non-destructively and it'll still around as you transform the associated path. If you want to paint on the vector layer or apply filters destructively like 2.10, you'll need to rasterize it first (which removes the connection to the path). You can revert the rasterization if you want, but that'll remove your destructive edits.
I'm working on vector layer masks (see: CmykStudent: "One last "big" feature I'm try…" - Fosstodon), which will be non-destructive and will keep the layer mask attached to the path. For now, those three operations you mentioned are still destructive and so there won't be an association with the path and layer.
Oh yes !!!
At first, I understood "masks on vector layers", and told myself: "but it already works" (on 3.2rc). Then of course I got it when clicking on the link. That's huge!
I can't thank you enough for your remarkable work within the GIMP team!
Speaking of masks, I have experimented with the new workaround suggested by Jehan for "simulating" adjustment layers with empty layer groups on passthrough mode. It's great, but makes more obvious an issue that I have observed since layer masks on groups exist. If you put layers in the group, and the smallest layer is smaller than the image, the group mask gets cropped to the layer's size. My workaround was to always put an empty layer with full size inside the group.
But now the issue becomes even more annoying, because you can't "regrow" the hidden mask of non-destructive filters. And there are a few weird behaviours linked to that issue for attached filters (even for a single layer). Don't know if my description makes any sense. I should have reported that bug already, but you know how time flies...
