mhmm the only use i have of that currently would it make harder to use 
with a separate enum
(also we'd copy the type with `to_string()` once more)

e.g. i use

`resource.resource_type().starts_with(...)`

with a separate enum it would be

`resource.resource_type().to_string().starts_with(...)`

which is more to write and one string copy extra...
