Next Generation PSR,
What a load of rubbish.
I hope to work as cabin crew for a while before continuing my education, and eventually becoming a pilot. If I/George/Anyone applies to an airline and gets accepted as cabin crew, it's because the airline wanted US for the job - not the other person who may want to be cabin crew for their full career.
And for your information, it is not "pretty much frowned upon" - and yes, I am speaking from experience.
If you have the ability to fly an aeroplane, and also the ability to be cabin crew, why shouldn't you use one to get into the other.
Should a low hour CPL not work as a flight instructor until s/he can build enough hours to get his/her first airline job? It would seem not, as that would be using one as a "steping stone" to the other.
If you are, as your name suggests, a purser, should you have taken that promotion? Aren't there many others who are still junior cabin crew that would have wanted that job?
I know George, and I know she is an excellent pilot. However, I also know her great personality, and what an excellent cabin crew she'd make for those first few years.
Go for it George!
