Any programming language that offers a generic boolean type uses a byte anyway. Or you can use a CHAR(1) and set it to Y,y/N,n, but string comparison structures are more annoying. Very useful though if 'human/non-binary-aware' users have to deal with the data and you don't want to bother converting the 0 to No and 1 to Yes. Or you can use ENUM with Y or yes, and N or No. Again, more annoying to write than TINYINT but more human-readable.
