"Not common" does not mean "you shouldn't care", when you are writing
a library that could potentially be used in more exotic architectures,
such as the one mentioned in this thread.

For example if you are writing, say, a small library that calculates
hashes or checksums using a particular algorithm. It's not at all
unrealistic that such a library could have uses in these more exotic
microcontrollers (as microcontrollers are often used in embedded
systems that handle data somehow, and might be interested in calculating
things like checksums and hashes). And it is quite likely that such
an algorithm might care about bit sizes.
