So supposing you could teach only one 3-3 and one 5-4 joseki to the student which two josekis would you choose in this case (keeping in mind that you don't want to teach him a potentially inferior variation, regardless of how simple the sequence may be)?
That one's in the spirit of 5-4 josekis (at least the ones that settle). But today it seems taking territory is more popular:

To be fair, this is the way it looks because many times the 5-4 / 3-4 pattern arises because white has the 3-4 first and then tenukis after the high approach. Depending on the opening, it may still be a territorial style opening. We even see white tenuki after

, which was popular in games of Cho U, who had a penchant for early approaches.
What do you think of this one, which is still played?

I think if you're going to start with the 5-4, a plan like this is probably in the spirit, but you have to have the rest of the board in a position to support it. It's worth teaching and explaining that the right side is open for white.
In your example, consider this tewari:
$$B
$$ -----------------------
$$ . . . . . . . . . . . |
$$ . . . . . . . . . . . |
$$ . . . . . 3 2 4 . . . |
$$ . , . . . 5 1 , O . . |

elsewhere. Usually,

would be at 'a'.

in this tewari would seem soft, as we know that in the 5-4 variation, white has the option of tenuki instead of

, even though black 'b' would be a good follow-up.
So it wouldn't shock me if today someone thought it was good for white.
