Hey hey, hold on a second here. I have several repositories that I find very
useful, and none of them follow the bog-standard layout.

When I started using Subversion, I made my first few repos using the '/branches
/tags /trunk' layout because I had been led to believe it was the One True Way
of managing a repo. But shortly, I realized that Subversion was so flexible that
I didn't need to bother with such conventions.

It didn't take a long study session with the manual to figure this out, either.
Basically you just need to understand two things; namely, 'Copies Are
Cheap(tm)', and 'There's More Than One Way To Do It' (ok, everyone here
seems to use Python over Perl, but you get the point). Most of the stuff I keep
in my repos isn't even code, thanks to Subversion's handling of binary files &
MIME types, and creative layouts can be very helpful.

Anyway, I don't disagree with the idea of repository templates. They can be
useful, especially if you are creating repos for C projects all day. I don't
even object to having a template applied by default, as long as I can turn it
off. But I do take issue with your statement that repos without an authoritative
structure will cease to be useful in the long term; and I also think you are
overstating Subversion's 'barriers to entry'.
