Oh really? That would be news to the folks that make the charts.

I think not. The charts are marked in the standard way to indicate the
vertical boundaries of the SFRA. All sectors start at the surface, although
the ceilings vary.

Apparently you have never heard of shelving or floors. Take
example, Las Vegas Departure or Las Vegas Approach. Technically
Departure's floor there is 3500ft; at the ceiling of the pattern
altitude around Tower's airspace. Departure is split, to where a
sector's ceiling is 13000, while the rest of the next departure sector
has a ceiling of FL190[1].

Approach is the same. Their the first approach sector will have
their ceiling be at either 16000 or 12000[2], while their floor be at
8000. Next sector (final) has from 8000 until handoff to tower.

All of that information is available on the Las Vegas
Sectional, which you would have realized if you looked at it, since
it's publically available.

And to top that off, you can hear it in use on the KLAS
LiveATC.net feed.

BL.

[1] altimeter won't matter, as pilots will know that below
29.92, FL190 won't be used for a cruise altitude.

[2] Coming from the northwest, the crossing restrictions coming
into the Vegas Valley on a published STAR is 16000; MVAs in
area vary from 10500ft MSL to 14000ft MSL.
