This is convincing. I did not know that this format is explicitly
mentioned in the news.

Our general rule is that we do not drop existing features in Org mode
except extraordinary circumstances:
Especially when they are documented.

So, in the message I linked, Nicolas (the major Org mode contributor)
was not right. I hence need to fix the parser and update Org syntax
page. This includes fixing `org-element-clock-line-re' to account for
CLOCK: => 1:00 syntax.

Luckily, it does not look like we are going to break the existing
external exporter packages as long as they are using ox.el API -
`org-export-translate' works just fine with missing timestamps.

Yup. Although I did not see Nicolas' message that time. My judgment was
simply based on looking at the code and seeing that CLOCK: => HH:MM
matching was clearly intentional.
