Make all configuration resources abstract ?

Sure. ${idp.sealer.storePath} in system/conf/global-system.xml :

<bean id="shibboleth.DataSealer"
  class="net.shibboleth.utilities.java.support.security.DataSealer"
  p:keystorePath="${idp.home}/${idp.sealer.storePath}"

in DataSealer :

225 ... setKeystorePath(@Nonnull @NotEmpty final String path) {}
476 ... new java.io.FileInputStream(keystorePath);

The path would remain a string, but we would parse it as an abstract resource.
