I bought a used gaggia classic and when I was attempting to clean the dispersion plate I noticed this home in the sidewall. Is this supposed to be there?

Was thinking of replacing the part and shower head eventually but may need to happen sooner if so.

Looking at an early 2000s Gaggia Classic with:
PID
Silvia steam wand
Pressure gauge
Dimmer mod
top box / steam mods
Seller says it was rebuilt/descaled with new gaskets somewhat recently, used regularly after that, then sat for about a year before being tested again. Includes a few basic accessories.

Good deal for a first machine or should I pass? Any concerns with older heavily modded Classics?
