Yes, it's a misconception, since @srcset and <picture> are roughly
equally easy for an implementor to implement. The "prioritizing"
language is about valuing the *needs* of one group over another. For
example, if we rejected a suggestion because it was slightly harder to
implement despite being better to author, that would be prioritizing
impls over authors.
What happened here is simply that Hixie thought that one syntax (which
happened to be close to one suggested by someone on the Safari team)
was better than another syntax (which happened to be suggested by the
The <picture> proposal presented by the CG was insufficient to address
all the use-cases, as well. (In particular, the
resolution-negotiation use-case.) It can easily be extended to
address that, of course. (For example, by adding a @res attribute.)
If you did this, though, then you're back to two equally-powerful
syntaxes, and choosing one or the other based on personal taste. This
is what we *did* end up with, in reality, and @srcset was chosen

As far as I can tell, the majority of the anger over @srcset was due
to bad initial information. A lot of people thought at first that
@srcset was less functional than <picture>, and didn't understand the
functionality that it did present. Once all that misunderstanding was
cleared up (due to threads like this one), a lot of that anger
evaporated as well. Now we're back to a much simpler "I like syntax A
instead of syntax B" argument.
