While in general this should be fine w.r.t. breaking changes for the API itself,
as the name of those template-variables from the API path can be basically seen
as internal detail, it would IMO be warranted to state that explicitly in the
commit message, as FWICT this is basically the only time where changing the
parameter name mid-release is legit without some backward compat handling.

And just to be sure: you are certain that this cannot be passed anyhow else,
e.g. in some CLI (pvesh?) or other way?
