Hi,

Yes - everything should be fine when using the ET thornlist. I am
actually for the change you proposed (this is assuming simfactory only
enables thorns that are 'commented out' in thornlists).

I just wanted to note that simfactory has to work with other thornlists
too. And these thornlists might contain, say, thorn CUDA, commented out.
But that thorn (its source code) might not be present. In this case
simfactory would enable CUDA, which would break the build - possibly
surprising the user ("But CUDA is commented out - why does it try to
build it?"). We cannot assume every user of simfactory knows about the
'enabled-thorns' feature. It would be nice to be able to point the user
to the interaction between simfactory and the thornlist in that case,
telling them to either get the CUDA thorn, or remove it entirely from
the thornlist as commenting out does not necessarily mean 'do not
compile' with simfactory.
