yes of course, but this has proven to be very hard for us to keep this
pace within QGIS, especially when in SAGA fundamental modules like
io_gdal change parameters names without keeping retro-compability with
previous releases. Also modules change name frequently from one
release to another (as also their parameters). This is the main reason
we decided to stop trying support every latest release and so stick
with the LTR one.

Said that if the "official" way to support SAGA would be a plugin it
would be much easier to implement and distribute/update such changes.

cheers
