Is a Modern SharePoint Search Center also on the Modern SharePoint roadmap?

What I am looking for is a way to search seperately for both general content types and also for (company) specific content types. I want to be able to search through all these content types and being able to filter on a specific content type. I also want to be able to refine my search by selectable properties.

And I'm looking for a modern search center so it also follows the responsiveness, cross browser availability. Also it would be great when the search center can be styled easily, e.g. inherit the global Office 365 / specific SharePoint publishing styling, or it can more easily be styled than the current search center.

By content types I mean things like news, blogs, images, conversations, sites, groups, email and / or video's. By company specific content types I mean e.g. invoices, contracts, project sites, team sites, department sites.

At the moment we can create these search verticals by creating managed properties coming from indexed list items, documents or even site properties (using the property bag) and let the search query inside the search vertical only show these specific data. 

When a user searches for "Lorem ipsum" he sees all information related to "Lorem ipsum", when he switches to conversations, he only sees the conversations with "lorem ipsum" mentioned in the text. Pressing the invoices tab presents him all invoices regarding the "Lorem ipsum" customer. And when I've send a lot of conversations I want to filter by "Conversation Date". I can imagine that I want to be able to refine invoices based on invoice date, customer, or invoice paid yes/no.

Yes Adam Levithan, I'm a heavy user of Delve too, and I like it regarding people search, searching for documents and discovery of trending content. But at the moment I can't retreive specifically invoices, contracts or project sites. I can only filter by Word-document, which is too generic in cases of our customers.

I know that Delve is based on the Microsoft Graph and I can create my own solutions targetting Microsoft Graph. But I'm curious which direction Microsoft is going:

• Will there become a modern SharePoint Search Center?
• Do we have to create a Search Center experience using the upcoming Modern Publishing features?
• Or do we have to create a custom solution to realize a specific search center experience? E.g. an Azure Web App which targets the Microsoft Graph and uses Office UI Fabric to make it look consistent with other Office 365 services?

Like Mikael Svenson mentioned also, we are debating which one is better.

But like Microsoft also mentioned with other services (e.g. Teams vs. Yammer), we need the power of choice. Our enterprise customers have different search requirements than our SMB customers, for some of them Delve is magnificent, for others it is too simplistic because it doesn't suit them. So we need them both in our toolset.
