I came across this issue today where a library name that contains _append will trigger the old syntax warning for _append to :append.

ERROR: abseil-cpp-20240116.2-r0 do_package: Variable Requires: absl_config = 20240116, absl_core_headers = 20240116, absl_log_internal_append_truncated = 20240116, absl_log_internal_config = 20240116, absl_log_internal_globals = 20240116, absl_log_severity = 20240116, absl_strings = 20240116, absl_str_format = 20240116, absl_time = 20240116, absl_span contains an operation using the old override syntax. Please convert this layer/metadata before attempting to use with a newer bitbake.

I found I'm not the only one who has seen this issue:
https://community.toradex.com/t/how-to-add-new-abseil-cpp-to-image-please-convert-this-layer-metadata/21212/5

I'm looking for guidance on if this is something that should be patched, reported upstream to bitable, or maybe there's an insane skip that should be applied?
