Spring Add URI variables to request context in AbstractUrlHandlerMapping (reactive)

There seems to be an asymmetry between MVC and Webflux with the AbstractUrlHandlerMapping. The MVC one parses out the URI variables and dumps them in a request attribute. The Webflux one does not. Here's what I did:

class MyHandlerMapping extends AbstractUrlHandlerMapping {
    @Override
    protected Object lookupHandler(PathContainer lookupPath, ServerWebExchange exchange) throws Exception {
        Object result = super.lookupHandler(lookupPath, exchange);
        if (result == null) {
            return result;
        }
        PathPattern bestPattern = (PathPattern) exchange.getAttributes().get(BEST_MATCHING_PATTERN_ATTRIBUTE);
        Map<String, String> uriVariables;
        Map<String, MultiValueMap<String, String>> matrixVariables;
        if (bestPattern == null) {
            bestPattern = getPathPatternParser().parse(lookupPath.value());
            uriVariables = Collections.emptyMap();
            matrixVariables = Collections.emptyMap();
        }
        else {
            PathPattern.PathMatchInfo match = bestPattern.matchAndExtract(lookupPath);
            Assert.notNull(match, () ->
                    "Expected pattern to match lookupPath " + lookupPath);
            uriVariables = match.getUriVariables();
            matrixVariables = match.getMatrixVariables();
        }
        exchange.getAttributes().put(URI_TEMPLATE_VARIABLES_ATTRIBUTE, uriVariables);
        exchange.getAttributes().put(MATRIX_VARIABLES_ATTRIBUTE, matrixVariables);
        return result;
    }
...

(Code copied from RequestMappingInfoHandlerMapping.handleMatch.)

Would it be reasonable for that to be the default?
