We discussed the in discord that the downgrade is being constrained by DWDS.

Unrelated, it looks like there may be a Dart compilation failure with this change from CI:

packages/flutter_tools/lib/src/base/analyze_size.dart:152:51: Error: A value of type 'InputStreamBase?' can't be assigned to a variable of type 'InputStream?'.
 - 'InputStreamBase' is from 'package:archive/src/util/input_stream.dart' ('../.pub-cache/hosted/pub.dartlang.org/archive-3.2.0/lib/src/util/input_stream.dart').
 - 'InputStream' is from 'package:archive/src/util/input_stream.dart' ('../.pub-cache/hosted/pub.dartlang.org/archive-3.2.0/lib/src/util/input_stream.dart').
      final InputStream? rawContent = archiveFile.rawContent;

Thanks for the fix. customer_testing on cirrus will unfortunately only be fixed by a rebase (not merge) upstream.

SkiaPerf is reporting a ~20ms improvement in DevFS sync time on this change

Is that expected?

There weren't any changes in DDS or the service that should have impacted DevFS latency, but if we're seeing a consistent improvement I'm not going to complain... :-)
