Hi Nilesh,
Thank you for you offer. I'm sorry, I completely forgot about this bugs.
I wanted these libraries (#921150 and #922528) to be uploaded in order
to package the latest 'arduino-builder'. However, we finally decided to
keep the current version since 'arduino-builder' will be superseded by
'arduino-cli' in the near future anyway.
I would not close the ITPs nor remove the work from Salsa since I suspect
they will be necessary for 'arduino-cli' though I haven't looked into
this yet. I guess the RFS (#934515) could be closed as "wontfix" and/or
tagged as "bullseye-ignore" and simply left open for later. I'm easy.
