As far as I know, libsoc is still being actively supported and if there's an 
API change, it should be fixed in no time. That's why I'm copying Jack here, 
who is an active OE developer here.

As of having an alternative for other potential users - there's nothing wrong 
with it. But, acceptance criteria into OE-Core is quite high, especially when 
there are alternative solutions already available. That's why I'm asking if 
it's any better than the other solution. In other words, why libgpiod should 
be accepted to OE-Core, but not libsoc? Maybe it should be submitted to 
meta-openembedded layer instead?
