You'd think, wouldn't you?

But yes....what you say is correct. In reality bolts shouldn't be in shear at all if they're done up correctly. I can add more detail later, but personally I'd think very carefully about where and how you use titanium bolts.

Edit: in reality though, when talking about an aluminium thread, I also don't think you can do a titanium or high end steel bolt up tightly enough to notice the difference. You'd strip the female thread first. Its actually a really complicated science :D

So , yes it should be okay?
Obviously as the bike weighs about 1/2 tonne it’s not about weight saving - just availability

I wouldn't, not yet anyway.

I'm more curious as to why the replacements are so expensive. What are they exactly? I'd expect steel bolts to be pennies...although maybe not if you're only buying a few.

Post a pic of the bolt? It's often just a case of knowing the proper name for it and hence being able to Google.

If they are just a bit manky looking,I'd hit the heads with a wire brush in a drill,then either lacquer them,or ACF50.

That's the cheap option!
