Seriously, current versions are barely usable, and I don’t think I’m doing anything particularly hard. Want to verify your config before committing to it? Nope. Want to delete a vlan? Not happening without bypassing netplan. Want to bring up a vlan on an interface with a long name (which is the default on a fresh Ubuntu install with a NIC in a PCIe slot)? Netplan will accept the configuration, but it won’t work, and you’ll have to do quite a bit of digging to find out why your vlan doesn’t exist as far as the kernel is concerned.
The latter one is nasty if you upgrade Ubuntu on a system where the management interface is on a vlan.
