Gold Saucer mounts - it's been a while

[Mirvana]

The most recent Gold Saucer mount was actually added ~6 months ago, not "over two years". (Magicked Card)
Not really that unreasonable for SE to be focused more on the brand new expansion's launch than target big updates to niche content right off the bat.

If we're talking just "need more things to spend MGP on", I'd much rather them add untradeable consumables (ex. Cordials) to the prize lists than more 1-time-buys like cosmetics/furnishings anyway. (Though I'm still dreaming of my 9999999MGP "It's actually just Godbert carrying you around himself"-mount. Do it SE!!)
