It seemed like you were saying that one's own code would be
accidentally relicensed to GPL if you included GPLed code. You
ellipsized some critical nouns. :-) And it seemed to me that only this
drastic interpretation would warrant dramatic red flashing warning

In any event, I would not use "relicensing" to describe accidentally
labeling GPLed code as BSD. Only the copyright holders are able to
relicense. Anyone else going through the same motions just commits an
incorrect statement of fact. One that is usually trivial to discover
since most people, in my experience, do keep a note of where they got
a function from when they do copy-paste a snippet. If something goes
wrong, you want to know who to blame and where to get updates from.
