As discussed below, there are too many problems and uncaught bugs in the parser when trying to support proxies having similar names but different types. There's specific code to detect the presence of stick-tables in a pair of such proxies for example. It's even possible that certain combinations of backend+listen that were not previously detected have some nasty side effects. According to the proposal in the discussion, this is now deprecated in 3.1 (thus we emit a warning) and will become forbidden in 3.3. A backport might be useful, but reporting a diag_warning only, not a classical warning, so as not to break setups running in zero-warning mode. It was verified with a config involving all 9 combinations of (frontend,backend,listen) followed by one of the same three that all collisions are now properly blocked and that only back+front are kept and emit a warning.
