I've never read that before.  Learn something new etc...
It seems path prefixes aren't good nor even commonly used.

A review of kernel patch subjects:

$ git log --no-merges --pretty=oneline | \
	cut -f2- -d" " | cut -f1 -d: | sort | uniq -c | sort -rn

is interesting.  Here's the head:
   5007 x86
   3943 Staging
   3220 USB
   2790 sh
   2707 KVM
   2624 ARM
   2449 ALSA
   1571 Input
   1549 ASoC
   1470 iwlwifi
   1423 ACPI
   1397 mac80211
   1384 V4L/DVB
   1226 sched
   1200 Btrfs
   1184 powerpc
   1106 [NETFILTER]
   1080 MIPS
   1049 net
   1047 ide
   1014 drm/i915
    993 staging
    921 ath9k

Some subsystem maintainers like upper case, some mixed, some lower.
Some aren't consistent.  (Staging/staging)

It doesn't seem a rule can be pregenerated so maybe adding these
"C:" lines to MAINTAINERS has some value.
