We want the flavor name and flavor id to have the same value. This was working fine until we added a flavor name with '+'.
In the code [1], the flavor id is restricted to '^(?! )[a-zA-Z0-9. _-]+(?<! )$'. Although the comment above that code says 'forbid leading/trailing whitespace' -- it is restricting more than the whitespace. In the api-ref [2] for creating a flavor, the id is described as "The ID of the flavor. While people often make this look like an int, this is really a string. If not provided, this defaults to a uuid."
I haven't seen anything that explicitly indicates that plus signs are not allowed, so it seems to me that this is a coding bug and that the plus sign (and perhaps other characters) ought to be allowed as part of the flavorid value.
eg, try creating a flavor name & id with 'this+that':
$ openstack flavor create 'this+that' --id 'this+that'
BadRequestException: 400: Client Error for url: .../nova_api/v2.1/flavors, Invalid input for field/attribute id. Value: this+that. 'this+that' does not match '^(?! )[a-zA-Z0-9. _-]+(?<! )$'
Tested against master branch (of nova and openstackclient).

We don't allow the plus sign as you saw in https:/
Accepting it as a doc bugfix, not for telling yes for modifying the API as it would need a new microversion (and a spec)
