its an inyan
i hold by it
not everyone does
i once saw a very chushiv Rosh Kollel, who is also a Posek, blow out the candle he used to light the Menorah.
i was quite surprised and asked one of the Kollel men who said he alwaus does that, rather than create a tircha d tzibbur for the extra few seconds to struggle with waving it out. he said the R’K does hold by not blowing out a candle but it is a minor consideration when something else outweighs it.
