Just a small FYI about seq.el, for those who may not be aware: while
it's a very useful library, it can be quite slow since it uses generics.
For example, here are some benchmarks comparing seq-intersection with
other functions that intersect lists:


Note the last benchmark listed, which shows that cl-intersection is
about 2x as fast as seq-intersection.  As well, dash.el's -intersection
is about 17x faster than seq-intersection.

So while seq.el will undoubtedly be useful in Org, it should be used
carefully with regard to performance.  Type-specific functions will
generally be much faster.  And as long as dash.el can't be used in Org
proper, a custom implementation may be called for at times.
