Inconsistencies between terraform and pulumi providers (v0.50)

[simplg]

I've been trying lately to migrate some of our infrastructure managed by terraform to pulumi. When trying to do a POC, I've encountered some discrepancies between the two providers.
From what I've gathered from the version number and the way the commits are made, it seems this pulumi package is generated from (or at least based on) the ovh terraform provider. However, it seems that, while the Get endpoints do seem to match between the two providers, the creation/update endpoints aren't.

For example, the GetNetworkPrivateSubnet does seem to retrieve the same informations as the terraform ressource provider v0.50 (GatewayIP, Allocation pools, ...) but the NewNetworkPrivateSubnet doesn't allow to set either GatewayIP or Allocation pools.

I forgot to mention that I'm doing the POC in go but I've seen the same discrepancies (for network subnet) in the typescript package.
