I thought the whole point of DBI is that once you have a DBI handle the perl code by and large does not need to know what the driver is

Ideally, yes, but it's overkill to write a database engine that parses and processes INSERT and SELECT statements if your goal is to produce statement handles that read arrays (something very useful, particularly to database drivers).

As such I don't see why the Sponge module is in the DBD space let alone shipped with DBI.

DBD::Sponge is usually used by other database drivers. As a building block for building database drivers, it is fitting for it to be in DBI.

As such I don't see why the Sponge module is in the DBD space

Where else would you put a DBD?

I was more looking for defences and criticisms of them as solutions.

DBD::Sponge: Unless you're testing a module that expects nothing but executed statement handles, not useful. Sorry, I thought I had made that obvious.

DBD::Sqlite: No criticisms, thus my post. It's supported by popular ORMs, so it's excellent if your app/distro uses such an ORM.

Why would DBI be installed on a test machine but not a sensible driver?

Who cares. The installer handles all that for you.

The question makes no sense anyway. A sensible driver for one purpose is not sensible for another. A particular driver that's sensible today won't be sensible tomorrow.
