PoP states "The store-clock-fast facility *may* be available on a model
implementing z/Architecture."
The "may" word forces my performance sensitive code to go through additional
controls before using STCKF, which sort of defeats the purpose of the
instruction.
STCKF was first introduced in 2
Consider
X DC A(FOO) Where A is *not* external to the assembly
ORG *-4
DCF'0'
What will X contain at runtime? I have not tested, but I am going to go out on
a limb and guess "the load address of the CSECT containing FOO."
I will leave "why" as an exercise for the reader.

With regard to the first one, I don' think it will generate any ESDs unless you
code EXTRN (or similar) for each of your whatevers.
If you do so, then I think HLASM generates an ESD even in cases where a human
could tell it was problematic coding. For example
EXTRN FOO
DC A(FOO)
ORG
