Never say the Locrian mode is non-composable again!

I read online that the Locrian mode as a key is just theory and really can't be used to write entire composition in but I've managed to do it! Ever since then just the fact of it being not used drove me to prove people wrong. My typical chord progression of Locrian Would be Im7b5 - V - IV - VI In B locrian would be Bm7b5 - F - Em - G I played a song with the progression C#m7b5 - G - F#m7 - Aadd9 Ending on C#m7b5 of course. And someone told me it was beautiful. I asked them if it sounded strange to end on the last chord and they said no. Any thoughts?

Well, is this the place where you found the information?

If it isn't it would be nice if you could link the right link.
Anyways, I don't really know anything about composing so I don't really have any thoughts about it.
