Why this change? This is logically an assertion, so it's cleaner to express it as such.

Just like in C/C++, adding a unit test that violates an assertion is not worth it.

Why add encodeURIComponent here if it's not needed?

It seemed too lenient to allow a range violation of this kind get away with an assertion. Additionally, it would allow for testing this code path. The way I interpret it, an assertion is an error and should be treated as such; especially in production code.
However, I do see your point that it may not be worth it to test this assert violation. Moreover I concur that it would be cleaner to express it as such. I will revert this change.

Mostly as a security mechanism to not trust date input and as a result avoid unexpected or erroneous requests to the server. In my performance profiling, this had minimal effect and can provide security benefits.

Thanks for the review, Alexey.
