I thought Menzoberanzen was a systemless book with no real crunch.
I strongly suspect 4e FR sold poorly, just wouldn't use that one book as an example. The Spellplague fixed one major problem (Mystra) but after reading it over I realized I hardly recognized the setting anymore. Yes it had problems that needed fixing, but they just needed to be excised.
So now in 5e, FR has Mystra again. I see nothing to recommend it over 3e or earlier Realms.
