I am always a bit skeptical about these approaches (i.e. providing a
general wrapper) because you either have to agree on the least common
denominator of features or have to implement features in the wrapping
layer. In any case the wrapping layer needs to be updated whenever one
of the backend changes, which potentially creates a lot of maintenance
effort.

Also, especially with REXML in the mix I believe that had some quirks
related to encodings in the past. So generally testing effort will be
quite high. My 0.02€.

If only a few operations are used then the situation might look
different. Still you add one dimension to the test matrix because you
have to test all target system configuration combinations.

Kind regards
