String reboot - (1a) incidental whitespace

So let's move on to the follow up question. If you replace concatenated
strings -- which can have exactly the right amount of indentation:
String s =
"public class Foo { \n" +
" void m() { }\n" +
"}";
with multi-line strings:
String s = """
public class Foo {
void m() { }
}
""";
you've gained one thing (dropping the concat and escapes), but have
inherited a bunch of additional incidental leading whitespace. And
we've talked about two paths for that, the implicit one (where we
auto-align, in the absence of reasons not to), and the explicit one:
String s = """
public class Foo {
void m() { }
}
""".align();
What can your data tell us about how often you care about incidental
whitespace, and how often you'd be saying ".align()"?
