Yeah, I think the same thing. Probably the reason you don't hear much about it. The sixth is altered which to me is a big part of any major chord progression. The harmonic scale itself isn't particularly used for chordal composition, just like the harmonic minor. I don't rule against using it, but I find it is a hard scale to work with. Even for harmonizing over a major chord, it is almost useless. The b6 automatically conflicts with the 5th of the root chord. There's not even a major chord with a b6 in it. Alot of things in my mind go against this scale.

The only use I see with the scale is for a bass player, who would want to play a major 3rd below the root. Here a tab example.

C major
(guitar)
E:--0--
B:--1--
G:--0--
D:--2--
A:--3--
E:-----

(bass)
G:-----
D:-----
A:-----
E:--4--

That's about it, so I see very little use of this scale for a guitarist. Even for the bass it is very uncommon.
