From what I've learned, the grass strips in England and Europe were actually just huge fields with no official runways. The aircraft simply lined up into the wind and took off. Aircraft like -109's, Spit's and Hurri's (with extremely narrow gear) don't care for the side loads that happen with crosswinds. I think it could even go further back, as far as WW I, when aircraft didn't have brakes or tailwheels and needed to land into the wind for safety.
It's interesting how much a modern perspective directs our thinking. Cart, horse, chicken, egg!
Landing
directly into wind has always been a better idea than not. Today's runways, therefore, are the compromise, not the original large (ideally round) field that, AFAIK, was the international standard - mostly up to W.W.II.
As Rick says, in Europe, the UK, and most of the globe, prior to W.W.II airfields and airports didn't have designated runways but landing areas. I'm not familiar with US practice in that period - anyone?
One of the reasons flying boats were popular up to W.W.II was that grass fields, the vast majority of airports then, were not good for heavy aircraft. The British experimented with 'accelerators' to get laden bombers off, as well as going for the more familiar runways.
As we know, runways bring numerous benefits and traffic, lighting load etc, but we also accept the out of wind payoff on aircraft structures as well. (Video footage of the new Airbus undertaking crosswind acceptance in Iceland demonstrates what a big ask that is.)
Linking to the comments in another thread on German vs British serviceability in aircraft design, the Messerschmitt 109s narrow gear enabled rapid rail shipping as it was attached to the fuselage, and thus a 109 sans wings could use its own gear to be moved. The Spitfire was a design compromise, neither as useful not so narrow, 'toed' or difficult as the 109's. However it was neither wide like the Hurricane's nor did it support the aircraft with the wings off. The Hurricane had a wide track gear (definitely NOT narrow) so it could cope with rough fields, as did all Hawkers of W.W.II. All three types mentioned were expected to used fields, not runways; but utility overcame practicality in the case of the 109.
The Germans found captured B-24s somewhat problematic on grass, and lost a couple due to nosewheel collapses.
The Operations Officer of the RAAF Museum was asked after he'd landed the RAAF Museum's Winjeel on grass at Point Cook this week why he used the grass, by a member of the public.
As well as the tailwheel preference mentioned above, he added that it meant he was closer to the audience.

However he also added that normally, Point Cook's grass strips have some 'give' and are better, but with the current dry conditions, they can be very bumpy due to the soil erosion between grass clumps.
