I think that bloat is an important issue. Systems with limited resources need
to run coreutils. Would a smart watch need to print a sequence of letters to
run?
Adding letters creates issues with loading unicode character set tables and
creeping featurism if later seq needs to implement all of the listing methods
common in word processors (upper case, lower case, what happens after z, roman
numerals, etc.)
It breaks the unix philosophy of doing one thing and doing it well.
If you need a sequence with letters, you can always use another filter to
convert numbers to letters, for example,
seq 1 10 | awk -e '{ printf "%c\n", ($1+64) }'
or
seq 1 10 | perl -e 'use strict; use locale; while (<>) { printf "%s\n", chr($_
+ ord("a") - 1); }'
or
seq 1 10 | perl -e 'use strict; use Roman; while (<>) { printf "%s\n",
Roman($_); }'
