Two problems with that option:
- first, it is not acceptable; one must *not* select a symbol that is
part of a choice
- Kconfig won't even act on that select, in fact:
$ cat select-choice.in
config FOO
bool "foo"
select BAR_B
choice BAR
bool "bar"
config BAR_A
bool "bar-a"
config BAR_B
bool "bar-b"
config BAR_C
bool "bar-c"
endchoice
$ cat .config
#
# Automatically generated file; DO NOT EDIT.
# Configuration
#
CONFIG_FOO=y
CONFIG_BAR_A=y
# CONFIG_BAR_B is not set
# CONFIG_BAR_C is not set
So, as you can see, even though FOO is set, BAR_B is not, even though
FOO selects it.

One alternative (if we are *that* concerned with user-friendliness),
would be to introduce an intermediate symbol that allows to get rid of
.py, something like:
config BR2_PKG_PYTHON_WANTS_PY
bool
choice
bool "module fomat"
config BR2_PKG_PYTHON_PY_ONLY
bool ".py only"
config BR2_PKG_PYTHON_PYC_ONLY
bool ".pyc only"
depends on !BR2_PKG_PYTHON_WANTS_PY
endchoice
(note: .py+.pyc option voluntarily omitted).
and then Kodi would select BR2_PKG_PYTHON_WANTS_PY.
But that's just ugly, even just for the sake of simplicity.
