For Fuseki-specific solution:
LATERAL may work
WHERE
{ VALUES ( ?this ?Container ) {
( <https://localhost:4443/whateverest/> <https://localhost:4443/> ) }
LATERAL {
SERVICE <http://fuseki-end-user:3030/ds/>
{ GRAPH ?Container
{ ?Container a ?Type }
}
}
}
It's Fuseki-specific (ATM) becuae it needs to rewrite the SERVICE block.
Normally, that's an alegbra rewrite but for SERVICE it needs to recreate
query syntax and it's using LET currently.

LET is an ARQ extension like BIND except if the variable is already
bound to the same value it passes the soltion, and if it is a different
value does not match. So it is a combination of BIND and FILTER sameTerm
and is position insensitive unlike BIND.
