Why is this Self-Contained Change and not a System Wide Change?
It seems, at least to me, that it should be System Wide Change, according to https://fedoraproject.org/wiki/Changes/Policy#Complex_system_wide_changes .

== Summary ==
Upgrade bash to 5.0 release. This release fixes several outstanding
bugs in bash-4.4 and introduces several
new features. The most significant bug fixes are an overhaul of how
nameref variables resolve and a number of potential out-of-bounds memory
errors discovered via fuzzing.

== Detailed Description ==
There are a number of changes to the
expansion of $@ and $* in various contexts where word splitting is not
performed to conform to a Posix standard interpretation, and additional
changes to resolve corner cases for Posix conformance.
The most notable new features are several new shell variables: BASH_ARGV0,
EPOCHSECONDS, and EPOCHREALTIME. The `history` builtin can remove ranges of
history entries and understands negative arguments as offsets from the end
of the history list. There is an option to allow local variables to inherit
the value of a variable with the same name at a preceding scope. There is
a new shell option that, when enabled, causes the shell to attempt to
expand associative array subscripts only once (this is an issue when they
are used in arithmetic expressions). The `globasciiranges' shell option
is now enabled by default; it can be set to off by default at configuration
time.
There are a few incompatible changes between bash-4.4 and bash-5.0. The
changes to how nameref variables are resolved means that some uses of
namerefs will behave differently, though upstream has tried to minimize the
compatibility issues.
== Benefit to Fedora ==
Bash is the default shell in Fedora and it will benefit from new
features and performance improvements of the latest release.
== Scope ==
* Proposal owners: Upgrade bash to 5.0
* Other developers: N/A (not a System Wide Change)
* Release engineering: [https://pagure.io/releng/issues #Releng issue
number] (a check of an impact with Release Engineering is needed)
** List of deliverables]: N/A (not a System Wide Change)
* Policies and guidelines: N/A (not a System Wide Change)
* Trademark approval: N/A (not needed for this Change)
== Upgrade/compatibility impact ==
Code related to resolving namerefs was changed, so some scripts may
break. But impact should be minimum as this release is largely
backward compatible.
== Dependencies ==
N/A (not a System Wide Change)
== Documentation ==
