I don't catch why people is so obsessed with indexing pages at all costs
It's like those that want to get AdSense approved with 100 visits/mo.
I could understand that if you are a top site with 50K/visits month and you have detected that a f*kr is copycatting your site you may try to index as fast as possible to get the first in rule (although, reputation itself could beat anyone even if the former has indexed first).
Also, in the most rare case, of a burning churn&burn site that wants to squeeze the max out of the last breaths, if it's not super-fast indexing it may mean that the C&B is not already profitting as well as it could be.
Obviously I can understand that an extra $5 profit can mean something to some, but to Google it doesn't mean a s**t.
RankMath instant indexing as
@Steptoe has already stated used the Google official API, which is great for what it is: announcing changes/edits in your posts, and remembering Google to index before sitemaps. It's plain adequate for its purpose. Anything beyond that is overpushing in 99,99% of the cases. Don't obsess to much with individual results in case they happen to you. Try to focus more long term if not a C&B site, and in that case, try to focus on churning and focusing on the most important things as much as you can, not on micro-specifics that burn the little time you have to achieve something.
