Possibly yes, if you're only contrasting it with being able to be faster.
I mean, it's sort of a false dichotomy -- it's omitting a "default speed" for writing boilerplate that is neither enhanced nor impeded.
the potential issue with an enhanced speed for writing boilerplate is that it means that there'll just be more and more boilerplate to maintain over time, and it's not clear what that cost over time will be.
How much more effort will be expended to replace things in multiple places? It exacerbates existing issues of "these two things look almost the same, but someone manually modified one copy...should that change be propagated?"
Meaning, it's essentially an ad-hoc code generator. Code generation can be a very useful technique (see protobufs), but without the ability to re-generate from a source?
Perhaps a possible enhancement might be for copilot to keep track of all blurbs it generated and propose refactoring/modifying all copies?
