Question for the knowledgeable engine people on the forum;

I'm currently stripping my engine down for a full rebuild and I'm about to remove conrods pistons and the crank.
My Haynes manual recommends that I check the crankshaft endfloat before taking out the bottom end, to see if the crankshaft thrust race needs to be replaced - I imagine that most people will be glazing over now and switching to a more interesting topic 😉.
The endfloat on the crank measured bang on mid specification using a DTI gauge on the end of the crank.
My question is why wouldnt I just replace the thrust race anyway since I am going to be replacing the main bearings and shells. Is there a downside to replacing the thrust race as I cant imagine its very expensive?

Knowledgable feedback appreciated 👍
