My sense was that OP was referring to application wizards more so than
templates or macros.  In any event, I disagree with the notion that
where the fix is applied makes a fundamental difference.  To me the
difference is the probability of a programmer having to look at the
output of the generator.

To reveal potential bias: I have developed GUI applications on Mac and
Windows since early on (MacOS 2 and Windows 3) - I've written
applications for them from scratch, using skeletons and using wizard
generators.  I also have done a fair bit of bare metal embedded work,
and have created several DSL tools myself for various purposes -
including one commercial product.  Consequently I have spent quite a
lot of time over the years poring over code generated by various tools
... assembly listings, parser code, templates and, of course, the
output of my own DSL tools.

IME wizard framework code is simultaneously the least likely to be
looked at, but the most likely to require direct modification when
developing a non-trivial application.

DSL, template and macro generated code is more likely to have to be
traced through - because, charitably speaking, the errors and warnings
from compiling them, and the problems from using them quite often are
difficult to understand without doing so.  However, as you say, it is
the usual case that the problem will be solved in the DSL or template
source.

YMMV,
George
