# Steps when removing this entirely:
# Steps when moving these to `odisabled`:
# - Remove the old library from SYSTEM_LIBRARY_ALLOWLIST above.
# - Remove the `disable` and `disable_for_developer` kwargs here.
# - Adjust the `broken_library_linkage?` override below to not check for the library.
# - Remove the relevant `fail_on_lib*?`.
# If there's no more deprecations left:
# - Remove the `broken_library_linkage?` override and the generic alias in HOMEBREW_LIBRARY/linkage_checker.rb.
#
# Steps when removing handling for a library entirely (assuming the steps to `odisabled` has already been done):
# - Remove the relevant setting of `@lib*_found` in `check_dylibs` below.
# - Remove the `odisabled` line
# If there's no library deprecated/disabled handling left:
# - Remove the `display_` overrides here and the associated generic aliases in HOMEBREW_LIBRARY/linkage_checker.rb
# - Remove the setting of `@libcrypt_found` in `check_dylibs` below.
