the dB/octave specification of the crossover?

Hello,
I have a dumb question the dB/octave specification of the crossover. A speaker designer wrote on his Facebook that dB/octave is like the resolution of a television. For example, for the same set of drivers, if we apply a crossover with 12dB/octave, the sound won’t be as detailed as with a 50dB/octave crossover. If this is true, I wonder why there are many speakers with 12dB/octave only. Why isn't there a race in dB/octave just like 4k, 8k TV?
Thank you.

Thank you everyone for the valuable input!

On his facebook, he builds speakers with TAD, JBL, Altec drivers. His crossovers looks very massive and impressive. I have been following his page until he made this statement which puzzled me a lot because there exist some hi-end speakers with only 12dB/octave.

I'm not an electrician either so I will check out Danny Richie video clips about crossover. 

@twoleftears :  I won't :)

@erik_squires  I have been thinking of building speakers with full-range Audio Nirvana drivers (which doesn't require any crossover) for my parents. 

The Sea A26 kit looks to be more room friendly and really nice. I will check it out. 
Thank you.
