Not sure about that - a lot of the Western support for Ukraine has (and there is a really good example of this mentioned in your post) been of the ad-hoc and un-coordinated kind. Supplying three different sorts of IFV Ithe French are also supplying one with the AMX-30s) is going to cause more logistical problems than supply the same overall amount of one IFV type would, and I think countries should focus on that rather than assembling a mish-mash of bits of kit working alongside a mish-mash of Soviet era stuff, all using different ammo.
It should really have been sorted out long before now who was going to supply and then continue resupply of whatever bit of kit for as long as is required. This should be easy with the common stuff (MLRS pods used by HIMARS and the other MRLS we've supplied, 155mm artillery rounds etc) but it needs to happen with the rest.
