How is your government wording quarantine? UK says it 'requests' or 'advises'

My partner picked up on something ridiculously obvious most people have overlooked it.

The UK population was issued a letter from the government outlining its 'request' and 'advice' that we stay in and quarantine.

At no point does it say its actually legally required, and at no point does the request state its an order.

It's merely a suggestion and that they would like us to follow these things and wash over about it being to protect the NHS.

Which spells it out quite clearly that this is all one big obedience test.

And we're all following it.

What about other countries, are any others being issued advice instead of official requirements?
