A major market for microprocessors were pocket calculators,
cash registers and the like, which is why having 8 bits and BCD
arithmetic was an advantage - see the DAA instruction of the 8080
or the decimal flag on the 6502.

From 1978-1980 I worked at NCR corporation on cash registers.
We made a BASIC interpreter as the programmable backbone of
the cash register lineup. Not a single decimal arithmetic
instruction was used in the cash register application. The
BASIC interpreter was written by a 5-man team in 8085 assembler.
Quite interesting, thanks!
That model was sold from 1979 through 1998. So the lack of
decimal arithmetic was not a significant disadvantage.
The 8085 has DAA, as well :-)
However, at least the designers of the 8080 and the 6502 thought
that it was important, or they would not have invested silicon
in it. The 6502 people even had a patent on their direct
decimal arithmetic.
