I think that the general convention is to return status codes everywhere.
Callers then just check for success and otherwise then return the status code to
their callers etc until the "top function" is hit and does something with this.

So yeah, I guess a bool would be easier, but a status code is more consistent
with other functions which can return status codes (plus this means that callers
don't have to "invent" a status code if some function fails).

However, this is all just a matter of taste and if some code has good reasons to
do something else, why not?
