This reminded me of a caveat about using some of these abstractions – which is that they are still subject to the limits and restrictions of the underlying platform.

We discovered this the hard way once when an automatically generated function name or something was over the limit in prod (this issue [1] describes a similar problem). We did not catch this in dev because "dev" is one character under "prod" and our autogenerated name in dev hadn't put us over the limit. That was an interesting exercise in leaky abstractions.
