That's how the syncrepl protocol is defined. If this is a problem for 
you, then you should not use syncrepl.

Hm, for simple deletes this should not happen. It is explicitly checked 
in the test suite (scripts/test017) and definitely works.
Are you sure your shell backend has a Delete handler defined?

That specific problem probably still exists in the 2.2 provider. There 
are several cases where the 2.2 provider fails to detect changes that 
should be propagated to refreshOnly consumers. In the 2.3 provider, 
using a sessionlog should fix all of these cases. Since the provider 
codebase has been completely rewritten for 2.3, I don't foresee any 
further provider-related fixes ever showing up in 2.2.
