Even with an intact PL-15E given to the Indians, they cannot replicate it.
If Koenigsegg were to give me the blueprints to their latest car and give me a sample, I could not build one.
India lacks the base industry and science/tech institutions and capabilities/awareness/mastery to replicate it. They are unable to manufacture the same components to the same degree. They can figure out perhaps the parameters of performance and get some ideas about what to do, perhaps even they have better ideas of their own. That's it. Replicating it is difficult and sometimes pointless.
The only sensitive thing out of the PL-15E wrecks that India has is probably just giving away some lessons in missile construction, basically all it gives Indian engineers are some pointers, many of which they would know already or possibly even have better ideas of their own. Wrecks also wont teach you how to defeat it since the wrecks don't give you access to the software, the exact performance of the rocket motor, the exact fuel composition and the guidance section is blown from the warhead.
The political and media narratives are just for morons and the non-military aware populace. All intended for political engineering, nothing more. Technically, PL-15E wrecks in Indian hands is the nothing burger of nothing burgers.
