Why doesn't _cat/recovery honor the bytes=XX in the URI?

I'm trying to change the units for the following API call:

GET /_cat/recovery?bytes=gb

The docs around the cat API imply that you can do this, but the recovery endpoint doesn't seem to work with this. The units are always shown in bytes.

Example:

GET '_cat/recovery?bytes=gb&v&h=index,shard,time,type,stage,source_node,target_node,files,files_recovered,files_percent,bytes_total,bytes_percent' | grep -v done | head
index                             shard time  type           stage source_node     target_node     files files_recovered files_percent bytes_total  bytes_percent
filebeat-6.5.1-2019.03.06         0     2.7h  peer           index rdu-es-data-01e rdu-es-data-01b 268   262             97.8%         218212992946 85.2%

filebeat-6.5.1-2019.03.05         1     2.1h  peer           index rdu-es-data-01d rdu-es-data-01b 271   262             96.7%         203869559392 77.1%

Which version are you using?
Do you see the same behavior with other APIs such as:

GET /_cat/indices?bytes=mb

It looks like this is an oversight in the code that serves the GET _cat/recovery API:

These values are returned as numbers, not as ByteSizeValues, so the ?bytes= parameter doesn't apply. Could you open an issue on Github, @slmingol?

Sure thing. I confirmed that other API cmds seem to honor the bytes=X

$ GET '_cat/indices?v&bytes=gb' | head -3
