We have a definite over reaction here and also goalposts are being moved to suit the situation. We cancel football matches but allow Cheltenham to go ahead. Why ? because lost revenue !! I then heard on the news today that Glastonbury will definitely go ahead. On top of that we have a Prime Minister who is showing us how to wash our hands and then refuses to be tested himself even after one of his own MPs has been tested positive. Madrid is in lockdown but we allow Athletico Madrid fans into the country ( I bet Liverpool wish they had called it off). Having said all that , with the decision that has been made, if the situation is worse on April 3rd there is no way they will allow football matches to be played. I can see this going on for 2 mths and the season will end early July. Euros then moved to 2021 and the new season starting in October.
With the greatest of respect, I think you're confusing decisions taken by UK government, with decisions taken by Football management.
The latest government advice (given on 12 March), was that schools wouldn't be closed & that mass gatherings (sport, Glastonbury etc) can go ahead.
It's football governing bodies that have suspended the competition, with an anticipated resume date of 3 April.
As you say, from information in the public domain, it's difficult to see that the health crisis will have peaked by 3 April, & therefore a resumption in the format that we are used to is unlikely.
As others have said, it's more likely that the footballing authorities are using the period to 3 April to work out a contingency plan.
IMO it's still the intention to complete the season with a deadline of 30th June, but it's a moving target, & there's a lot of "what ifs" to consider.
