Me too.
But its not only about becoming harder, I actually like the fact
that lamda exists as a tie in to the actual concept of an
anonymous function. When you read a math book on lambda calculus
its nice to transform those concepts directly to the language.

The current Pythonic lambda has its limitations, but being able
to explicitly create lambdas is a nice feature IMHO. Its much
better than having to create lots of one-off single use functions
with meaningless names.

It can't be that hard to maintain the lambda code, why not just
leave it there for the minority of us who like the concept?
