Please supply some references.  Here is a reference to doing quantile
regression with local logistic regression, but that is an alternative
to ordinary quantile regression, not to logistic regression.

AB - In this article, we propose a new nonparametric estimator of the
conditional quantile function. It is based on locally fitting a
logistic model. We compare the new proposal with some existing
methods. Those include the double-kernel technique of Yu and Jones
(1998), the adjusted version of the Nadaraya–Watson estimator
suggested by Hall et al. (1999) and the approach by Koenker and
Bassett (1978) based on the ‘check function’ loss. The comparison is
done by asymptotic mean squared error and a simulation study. The four
estimators have the same asymptotic variance, but their first-order
biases are different. We also propose a new automatic smoothing
parameter selection method in quantile estimation. We analyze the
finite sample properties of the quantile estimators using the proposed
bandwidth selectors. We find that the new method outperforms the
others in most cases of the numerical experiments. (References: Yu, K.
