If reporting is accurate from RIPE, Tata has 4,976 IP route entries and of that only 2,554 of those entries have valid RPKI. [1] Most likely in order to continue serving those who are unwilling or unable to deploy RPKI they work with their upstreams to exempt their announcements from being filtered due to invalid or missing RPKI. Unfortunately as long as companies continue to make exceptions as to who is exempt from RPKI route filtering the risk of someone announcing a bad route will persist with us. It would be awesome if every single IP resource was covered under RPKI but according to Cloudflare Radar, worldwide we’re only halfway there at 56.8% valid and 42.1% unknown/missing. [2] Fortunately we will never have another AS7007-like incident [3] but as yesterday proved can still be quite impactful!

Didn't RPKI and IR avoid any damage? If not, are there still relevant AS border routers that just accept anything?
