Nothing changed in that regard for a long while.

If you configure NM via managed=true, you tell it to read the
configuration from /e/n/i and configure the interface accordingly.

If you already have ifupdown enabled, this of course means that the
interface will be managed by two systems.
This is the reason why managed=false is the default.

If you want to use managed=true, you should consider
disabling/uninstalling ifupdown.

But it's much better to simply configure the interfaces directly via
NetworkManager and remove the interface configurations from /e/n/i.
