You will be amazed if you look what people still use these days for old stuff.
And main reason for this is the refusal of hosting company's to tell their clients to update stuff to not EOL crap. Too afraid to loose customers, so now panels are forced to support ancient stuff? That's the world upside down.
Example please check WP PHP stats

Totally not interesting. Users must be pushed to upgrade. If that wasn't done, people would still run Windows Vista or worse. Or you had to keep RedHat 5 alive to keep things working. So that is really a non argument. Most of those with php 5.6 are the happy few afraid to loose customers and keep ancient and unsafe stuff running to keep their customers happy.
Taking 7.4 into calculation, then 7.4 and 7.4 is 68.3% of the market. With the whole 7 range (where 7.0 is also EOL for example) it's even more.
Statiscs are nice, but safety is more important. And EOL versions are totally not important, so it's already fine if 5 versions are supported, because normally you won't have any more versions needed.
Probably you are one of the exceptions, so that is where DA is talking about, some exceptions wich can pay extra for the pro pack. Or pay extra and go over to CPanel, because Plesk also only supports max. 5 versions as far as I've seen.
So there is no reason to push something like that up to all of us, because most won't like to pay extra for something like that, which is mostly not usefull and at least insecure to use.
5 PHP versions should be enough. You could keep 7.0 amongst these 5 for that one customer, but hey... it's a business, also in Windows you can't use some old programmed stuff anymore in many cases. Life goes on, development too. Businesses know that, that's part of business costs. Maybe the hairdresse should have another one create a new site with wordpress.
We tried not once our clients persuade to change PHP currently supported versions.
Then you created you issue yourself, don't push of your mistakes to the panel.
and we can't force them to update theirs stack - it's theirs application,
Same statement.
This is plain nonsense. Just that's were (delivery) agreements are for. We have in our agreements stated, that the customers is not to compromise the server in any way, also meaning that thay have to use up to date versions of software and applications when needed.
So when we left php 5.6, we warned the customers 6 months up front, they could update their wordpress. Running old wordpress is also unsafe. And then we upgraded php.
By not forcing users to upgrade their stuff, you guys help keeping things like compromised servers, spamming via leak scripts etc. in place.
Sorry that I say it like this, but this is really what I think.
And if you think the customer is more important, oke that is your right do to so, but then don't go expecting panels to keep EOL and unsafe things supported, that is very unrealistic.
Oh yes, I don't know who brought this up, but this all has totally nothing to do with GPDR.
