That's a factor of the seals themselves, not whether "you ever used DOT3" as you wrote. Also you say that your problem was using DOT 3 which rotted the seals. So if anyone else had natural rubber seals and had used DOT 3, they would have had the same problem and had to replace the seals, and natural rubber haven't been used since the 50s or 60s. The bottom line is, if you have used DOT 3 and HAVEN'T had a problem with the seals, then they are not natural rubber and you can simply replace the fluid with DOT 4 or DOT 5.1.
As you say, I doubt whether any natural rubber seals still exist outside a museum.

I'll respectfully disagree, unless in the 31 years I've owned my '72B the seal technology has changed. It was well recognized in the 80's and 90's that DOT3 was the kiss of death for British brake seals. Maybe all those rubber based seals are gone now. When I first bought my B I topped up with DOT3 and within 2 weeks was re-doing my entire system. My mechanic was eager to point out the admonishment on the reservoir cap to use Castrol LMA DOT4.
