Extending uniformly continuous functions on subspaces to non-metrizable compactifications

The closure of $X$ in $Z$ is compact , so there is no hope if $f$ is not bounded. If it is bounded then so is its extension to the closure of $X$ in $Y$ and this gives a bounded uniformly continuous …

Tensor product of C*-algebras of bounded, uniformly continuous functions on metric spaces

The spectrum of the $C^\ast$-algebra of bounded, uniformly continuous functions on a uniform space is the Samuel compactification. So your query can be restated in the form: is the Samuel compactific …

Uniformities generated by metrics.

From your remarks one can see that the core of your question lies in the case of a product of metric spaces. But a large cardinal product, say of the real line, cannot have a structure generated by m …
