Right, we agree on the basics. Here's the challenge - the smartest
people don't sit down to write a simple snap. They want to make a snap
of the thing they care about, which is probably big and ugly inside
because it's been around enough for someone to care about it.
So, in that environment, learning snapcraft is a big layer of
indirection, and worse, if you hit the limits of snapcraft and have to
start writing a plugin, you are spending time and effort on something
you don't care about in order to get to something you DO care about.
That same person could probably MANUALLY construct a snap, as long as
they know what the constraints are. They can manually build their code,
they can build and copy, they can jiggle things to work.
I love snapcraft and believe we will make it perfect. But right now, I
see a lot of people hitting its limits and being baffled as to what it
is doing and why. Smart people saying "I give up because I can't even
get a bash script to work in a snap". That's a problem we must face head
on, not deny.
