Obvious as it is, if one of your peerings on an IX gets big in terms of in/out volumes, you HAVE to secure it by PNI.
You need a way to prevent the IX's equipments from being a SPoFs between you and that peer.
I'm not saying one should convert every single IX peering into a PNI, as I feel both are pretty much required: your smallest peers shall be secured on as many IXes as possible, your biggest ones via PNI. IX peering is mandatory to keep internet routing diversity up to par - and enable small ASes to grow.
Also, it is a wrong assumption to state that IX will make you spare money on transit, from my perspective they should be seen as securing multiple narrower paths to the internet.
