I removed DvcIgnoreFileHandler. I agree that it is unnecessary, but I am afraid that flag is not enough. It actually will not serve any purpose now that we plan to use dvcignore in each use case of walk. We need to pass tree object to access tree-related operations like `exists` and `open` which are required for ignore mechanism to work. I guess we could discuss usability of dvcignore in case of git branches, because that is the main obstacle in removing `tree` from ignore mechanics.
Suor: @pared what happens if `path` passed to `dvc_walk()` doesn't correspond the tree we use for ignores? This could be the same dir, but `path` means whatever we have on disk (Working Tree), which tree may go over branch. This will mean you will read files and ignore files from different branches, which will work some way most of the time, but is an obvious error.

So, the thing is we shouldn't pass path to `dvc_walk()` we should pass `tree` only and use it for both listing and ignore.
Suor: **UPDATE**. If we never need `dvc_walk()` to go by anything but working tree. We can still pass `path` and  set `tree = WorkingTree(path)`, we should not have to pass both path and tree.
efiop: I don't think it is working correctly. For example:
```
#!/bin/bash

set -e
set -x

rm -rf myrepo
mkdir myrepo

cd myrepo

git init
dvc init

mkdir data_dir
echo foo > data_dir/foo
echo bar > .dvcignore
echo bar > data_dir/bar

dvc add data_dir

dvc status

rm -rf data_dir/bar

dvc status

```

one would expect the last status to not show anything ,right? because bar was ignored. But it does show that bar was deleted.
pared: @efiop 
It seems I haven't removed os.walk in RemoteLOCAL.walk when writin initial dvc_walk implementation. Introduced proper change and test for that case
Suor: `dvcignore_raises` looks like cancer, there should be a better way.
pared: @Suor had the same impression, hence `[WIP]`, working on different approach
Suor: We need to stop complicating this. So I suggest the following:
- build `dvcignore` once, never update it,
- use cached property,
- pass `repo.dvcignore` to walks always, not passing is an error,
- do not construct `DVCIgnore` outside that cached prop with possible exclusion for unit tests.
efiop: @pared Please address DeepSource issues. I can see only `Method could be a function PYL-R0201
` issue being relevant here.
