Network filtering by MTU is not supported with the "net-mtu-writable" module

[kay]

Read-only (https://github.com/openstack/neutron-lib/blob/fc2a81058bfd3ba9fd3501660156c71ff1c8129c/neutron_lib/api/definitions/network_mtu.py#L51..L52) MTU supports listing, however writable "net-mtu-writable" (https://github.com/openstack/neutron-lib/blob/fc2a81058bfd3ba9fd3501660156c71ff1c8129c/neutron_lib/api/definitions/network_mtu_writable.py#L54..L56) doesn't support filtering by MTU:

Why do you think it is a wishlist? Read-only MTU filters list fine, but if you upgrade to RW MTU - it stops working. For me it looks like a bug.
