It depends. If you use the same stone from similar quarries and stick to a faithful reproduction that might be a good experience. Otherwise imagine McMansion levels of construction quality to rebuild the colosseum. That would be disgusting. Also visiting ruins is an amazing experience. You can touch stones that were put in place by humans millenia ago. If that doesn’t stir something in you then you’re a different kind of person than me.

The more common thing (now) is to make the new work high-quality but clearly distinct. I presume that's what's planned here -- don't build all the basement walls up again with similar stone to an original-style stage floor, instead add a steel structure over all the old stuff holding a modern floor, with glass skylights for touring the ruins below.

Notre Dame post-fire reconstruction has a similar issue. Some of the stonework, i.e. the naves, needs work. According to PBS Nova geologists & architects located the old quarries for different stone around metro Paris.

Notre-Dame never made it to ruins, though. It is a building that was still in use and still has a function to fulfil. And the people rebuilding it have a good idea of how it was before.

It’s quite different from patching up however we can something that was left to rot for centuries.
