Ok then I agree the qSupported idea makes the most sense.

Yeah, what I wrote in the doc wasn't correct either. lldb-server ends up using
a base of 0:
size_t count = packet.GetU64(SIZE_MAX);
uint64_t GetU64(uint64_t fail_value, int base = 0);
uint64_t StringExtractor::GetU64(uint64_t fail_value, int base) {
<...>
uint64_t result = ::strtoull(cstr, &end, base);
So it'll accept decimal, hex *with* 0x or octal. (lucky I've never seen anyone
0 pad the numbers)

I will revert it. I could correct it but that's opening the door to more
options and will just make the qSupported idea more complicated. (I'll update
the bug I raised too)
