Release pages have the option 'Delete this release'. However, the edit type is 'Remove release'.

Example:
http://test.musicbrainz.org/release/a65f18dc-b822-306c-bef9-8bc80e0dd5ba 'Delete this release'
http://test.musicbrainz.org/release/a65f18dc-b822-306c-bef9-8bc80e0dd5ba/delete (in url)

http://test.musicbrainz.org/release/a65f18dc-b822-306c-bef9-8bc80e0dd5ba/delete 'Delete Release'

I think alle occurrences of 'delete' should be replaced by 'remove'.
