My experience aligns with aakk9999. When I've seen problems, it's because the redirects were not executed properly, or other technical issues with the URLs made a mess that was hard to untangle.

Redevelopment of existing sites is a common occurrence, and though it does have challenges it doesn't not necessarily mean there will be lengthy problems because of "too many redirects." What can cause problems is many redirects all chained together for one single URL request.
