Anyone else's nursery say they shouldn't be bringing child to nursery in a buggy?

As per the title really, just wondering if anyone else has been told the same?

I started my DS turned 3 end of June to my older childs primary schools nursery in September. Received an email addressed to all parents a few weeks later to say they were shocked to see parents bringing kids in in buggies, and we should only be doing so if they have special need. Buggies are recommended up to the age of 3 and all kids are over this age now and children should be learning to gain strength in their legs etc etc. Now we have a 15 min walk in to school (30 mins if little one is on foot) and I have to get both kids in on time. We do usually walk home. Many parents drive their kids in to school or drag them in on a scooter, is this better? My eldest went to the same nursery and I initially brought him in in a buggy no issues, we stopped using a buggy before the end of nursery which is what I planned on doing with my youngest.
So, I'm just wondering if this is becoming quite widespread now among nursery aged kids?

To be honest I suspect what’s changed between 2014 and now is funded childcare.

We have a childminder absolutely insistent that ten years ago, the children she minded were drinking from cups, dressing themselves independently and walking rather than using buggies. Obviously the social and political landscape has changed considerably since 2014 but the only thing I can think of that would have dramatically changed parenting in that time is the lockdowns.

But the fifteen funded hours wasn’t introduced until September 2010, and this didn’t go up until thirty until September 2017. So while that isn’t an exact fit, if - and it is a big if - it is really the case that ten years ago Jannier was accepting independent, perfectly behaved children and suddenly isn’t, it seems more likely to me it’s a combination of lockdowns and perhaps ten years ago there weren’t as many children opting to use childcare for full sessions.

I am takin it with a heavy pinch of salt either way.
