Yes, but you have hundreds/thousands of these calls don't you?

If you have two calls here instead of one and that costs let's say
20 bytes of code and 1000 calls it's already 20K of binary size.

Perhaps code size is not your highest priority now, but
obvious inefficiencies like this are not good.
