The relevant range of Servo commits depends on a few dozens of Rust

the Rust team if they’re willing to add exceptions to their deletion
policy to preserve these specific versions. However some of these files
are already gone, we’d have to recompile them from source.
But more importantly, how much should we really care about all this? How
often have you used 'git bisect' in servo/servo, let’s say in the past
year? How much effort should we put into all this, compared to the
effort of manually finding and configuring working Rust and Cargo
versions if we ever need to build an old Servo version?
I have used git bisect fewer than 5 times in the past year. I think the
absolutely minimum we should do is provide clear instructions for how to
obtain missing versions and make the Servo build system use them; it
would be nice if that didn't involve building rustc from source.
