get-resource-counts, but excluding deleted ones

[Alberto Acebes]

(HAPI-FHIR 6.6.0, JPA)
In order to just 'count' the stored resources for summarizing purposes, seems that  the /<Resource>?_count=0 operation (or summary=count) are very slow when number of resources are starting to be big enough....
In paralell we have the /$get-resource-counts operation, that is low level, effective and fast, BUT it includes the resources marked as deleted (functional delete, entry remains) and is a bit confusing and creates misunderstandings.

I am considering to create a paralell  custom operation, or extend the current, to avoid included such deleted ones in the count, but I am surprised that it is not something already raised, since the conformance counters do not exclude eliminated resources either.

Is it because there is some alternative that I am overlooking?

Thanks in advance
