so are GoI and it's armed forces as per their own threat perceptions and resource availability. hence they are investing in multiple capabilities simultaneously, not limited to a few.
this is a academic paper on JSF programme from 97, notice how many times affordability is mentioned. also notice their original plans for JSF to complement with F-22. in 2024 neither affordability nor F-22 holds true anymore, this is to say battle landscape itself has changed since they started working on this.

my limited point being,
a few pieces of tech do not "win the war",
it's all available resources used in tandem that win the war. ultimately what is defining feature of a proper war, to send as much munitions for effect to barbad the other side aided by plethora of munitions delivery mechanisms , defend own side against incoming munitions. if India does go into a war, we might be looking at tens of thousands of tonnes of warheads that will be sent to the other side. out of this tens of thousands of tonnes of warheads, how much percentage will AMCA/Ghatak/FUFA send across? a small percentage in comparison, for specific tactical mission profiles.
these tech have their role to play, but entire burden of a win is not on them.
the reason i am making the effort to emphasise on this, is because i have the same issue with hype around brahmos especially the land attack versions.
note: leaving out many caveats like nukes, defensive doctrine, counter tech etc. to keep the scope of convo narrow and limited.
