This is all true, but not the point: cfajohnson claimed that sed is (or should be used) only for files. I challenged that claim by citing that
using sed in a pipeline would be a counterexample for an equally sensible use of sed.
Additionally you are correct in assessing the use of any external program in a loop to be expensive in terms of system calls. That doesn't mean it can always be avoided though. Sometimes there is simply no other choice because shell expansion is limited in its possibilities. If your problem can be solved by it, good, if not, you have to resort to some external program with greater capabilities even at the expense of system calls.

plymouth-set-default-theme
PLYMOUTH-SET-DEFAU(1) User Commands PLYMOUTH-SET-DEFAU(1)
NAME
plymouth-set-default-theme - Set the plymouth theme
SYNOPSIS
plymouth-set-default-theme [OPTION...] [THEME]
DESCRIPTION
When called with a THEME argument, the plymouth-set-default-theme command changes the preferred boot theme and also performs the necessary
regeneration of the initial ramdisk (initrd) since plymouth is loaded from the boot loader from the initrd prior to the mounting of the
root filesystem.
If plymouth-set-default-theme is invoked with no options or parameters, it shows the currently selected theme by default. This output is
used by the helper scripts plymouth-generate-initrd and plymouth-update-initrd to set the proper theme in the initial ramdisk.
OPTIONS
The following options are understood:
-h, --help
Show summary of options.
-l, --list
List available themes.
-r, --reset
Reset to default theme.
-R, --rebuild-initrd
Rebuild initrd (necessary after changing theme).
