<vector>: Superior string splitting (std::views::split) issue with VS2002 17.4 Preview 2

[fsb4000]

Describe the bug
An example from https://www.open-std.org/jtc1/sc22/wg21/docs/papers/2020/p2210r0.html#design doesn't work but it worked in 17.3

Command-line test case

C:\Temp>type main.cpp
#include <string>
#include <ranges>
#include <vector>

int main()
{
	std::string ip = "127.0.0.1";
	auto parts = ip | std::views::split('.');
	auto as_vec = std::vector<std::string>(parts.begin(), parts.end());
	return 0;
}

Well, I think this is expected now because: static_assert(!is_convertible_v<vector<char>, string_view>);
And they just need to change their code.
This code works:

#include <string>
#include <ranges>
#include <vector>
#include <iostream>
using namespace std;
int main()
{
	auto ip = "127.0.0.1"s;
	auto parts = ip | views::split('.');
	auto as_vec =  ranges::to<vector<string>>(parts);
	for (const auto& s: as_vec) {
		cout << s << '\n';
	}
	return 0;
}

$ main.exe
127
0
0
1

I answered that this is by design: https://developercommunity.visualstudio.com/t/10150447#T-N10150782

Closing as, as @fsb4000 points out, this is by design. Thanks!
